How to Analyze Battery Definitions

How to Analyze Battery DefinitionsIf you want to know how to analyze battery definitions then it is time that you become a part of this exciting topic. A battery is basically a set of chemicals and other substances that give out electric charge. These are the units of electricity that are used to generate electricity for use in your house. The supply of electricity depends on the number of batteries in your electric machine, such as the computer, or the electric light.There are different types of batteries, but most of them are quite similar. The main difference between these is the composition of the batteries. The types are the electrolyte, the plates and the separator. The electrolyte makes up most of the cost of the batteries. The electrolyte allows the batteries to work efficiently and conduct electricity, but only if it has good quality materials.There are many different types of batteries. One type is a pack. This is when you have one battery that charges the other. A secondar y battery is usually used to regulate the power used by the primary. It is used in vehicles, military vehicles, and for industrial purposes.These are actually a long range power source that can be used to run many electrical appliances. They are generally made up of different types of materials such as zinc-carbon, aluminum, lithium ion, lithium iron phosphate, sodium-based or even crystalline graphite. There are two types of these dry cell batteries; the graphite one and the porous ones.A battery that can handle large amounts of power, is called a supercapacitor. It can be put in cars, automobiles, power tools, and other devices that need to have large amounts of power. However, this type of batteries is very expensive and most people use them as back-up. It is an efficient way to store large amounts of power.An alternative to these, are the power packs. They can also be found in cars, but they are not as good as those used in cars. However, some of them still use a pack system to transfer electricity to the car. This makes it possible to reduce the size of the batteries, because it is much easier to put it inside the cars.There are some batteries that are designed for electricity, and there are others that are not. This makes it difficult to accurately calculate the number of cells to be used. A good resource to research this is Battery Demystified. A specialist can also help you with this.

5 Ways to Connect with your Online Classmates

5 Ways to Connect with your Online Classmates Image via Isorepublic.com Introduce yourself at the beginning of the semester Online classes usually start with a “get to know you” session that will allow you to introduce yourself to your new classmates. It is pretty much the online class equivalent of when professors go around the room on the first day asking everyone their name and major. Take advantage of this! Introduce yourself to your classmates by telling them your name, major, and your interests. You should definitely include your interests in your introduction, as it will make it easier to find friends in your online class. You never know if one of your online classmates loves the same band or TV show that you do! You should also respond to your classmates’ introduction posts if they mention something you are interested in. They will be glad to know they have something in common with you. If you want to connect with your online classmates, introduce yourself at the beginning of the semester, and respond to others’ introduction posts. Use the class discussion boards Class discussions can be an important part of a traditional class. Unfortunately, online classes don’t allow for this format of class discussion. For this reason, class discussion boards are important for discussions in an online forum. Participating in these discussions is good for your grade, because some classes will require discussion forum posts as assignments, and you might also be expected to respond to your classmates’ posts. These discussion forums are not only important for your grade, but also for your connections with your classmates. If you made friends during the introductions at the beginning of the semester, you can respond to their discussion forum posts, and they might even respond to yours! The class discussion boards are important for making friends in online classes, since online classes don’t allow for traditional classroom discussions. Follow each other on social media You might think it’s weird to follow people you don’t really know on social media, but if you have introduced yourself to a classmate during the introductions at the beginning of the semester and you have common interests, it won’t be weird! Communicating outside of the online classroom will help you form a stronger connection with these people. You can talk about things other than schoolwork, which will be quite a relief. So don’t be afraid to follow them on Instagram or add them as a friend on Facebook. (Later on, when you know them better, you can even exchange phone numbers and start texting.) You never know if these people will become your close friends! Have virtual study sessions Online classes can be very lonely, since it is not like a traditional class where you see your classmates three times every week. In a traditional class, you can easily ask your classmate if she wants to study in the library with you after class; but you can’t do this if you are an online student. There is something else you can do, though. You can hold virtual study sessions over Skype or FaceTime! It will be just like a traditional study session, where you and your classmates can work out problems or discuss the class material together. You will have the benefits of a group study session without physically meeting together. It will also, of course, help you connect even more with your online classmates. Schedule Skype study sessions before big tests, as it will help you not only prepare for the test, but also to make friends in your class. Meet up face to face If the online class is based in your local university, you might even be able to meet your online classmates in person! See if you can meet them for a study session (or even for lunch) on campus, especially if they physically take classes on campus (since they are likely to be there anyway). If possible, meeting one of your online classmates in person on campus will definitely help you connect with them. Online classes are convenient and great for many reasons, but they can get lonely because you don’t physically see your classmates. It doesn’t have to be that way, though! If you follow the tips I mentioned, you will make great connections with your online classmates.

How To Fix The Top 10 Cover Letter Mistakes Youre Making

How To Fix The Top 10 Cover Letter Mistakes You're Making Photo Credit: Rachael Cihlar/Trada.com 1. No Cover Letter.  This is one of the most common cover letter mistakes people make. Unless the company you are applying to specifically requests applicants not send a cover letter in with their  resume, a cover letter is needed. This problem has an easy solution:  write a cover letter. 2. Using a Generic Cover Letter. Using one general cover letter to send to each potential employer is lazy and shows you probably didnt follow the directions, as many companies ask you to answer specific questions in your cover letter. Also, by using a generic cover letter, you dont personalize your skills or mention the specific company. Having a rough cover letter template to use and personalize for each job is a much better way of ensuring your  resume is taken seriously and is a great way of avoiding this cover letter mistake. 3. Failing to Personalize.  Whenever and wherever possible, personalize your cover letter. Refer to the specific company you are applying to by name and dont just address your cover letter To Whom It May Concern or Dear Sir or Madam. By personalizing your letter, you show you have done your research into the company and know who will be considering your application, which is a subtle and good way of coming across as competent and detail-oriented. 4. Having Grammatical or Spelling Errors.  These common cover letter mistakes can be avoided by  proofreading, which is one of the most important things you can do before sending a professional letter in for consideration. Rereading your own work can help you catch mistakes you missed the first time around and spot places to tighten your writing. Also, writing in Microsoft Word or another writing application that has a spellcheck function is crucial as it will highlight for you where your spelling has gone awry. Lastly, check your grammar or ask a knowledgeable friend or family member to read it over for grammatical errors. 5. Hogging the Spotlight. Dont use your cover letter to just talk all about you; while this may seem counter-intuitive, potential employers want to read about what you will bring to their  company. So talk about your skills and accomplishments by writing how they would act as an advantage for you and be a  benefit to the business  if youre hired by their company. 6. Summarizing Your Resume.  Contrary to popular belief, a cover letter  does not  just consist of restating the contents of your  resume. The cover letter should provide a more in-depth look into who the company may be hiring if they employed you and you do that by talking about how your past employment experiences and skills would make you a good fit for the job (refer to #3). Photo Credit: iStockphoto 7. Handwriting a Half-Assed Cover Letter.  Writing a cover letter does not mean just scribbling a quick note or sticky to include before your  resume in your application. A cover letter has specific formatting and expectations that come with it and should never be handwrittenonly typed. 8. Formatting Incorrectly.  Your cover letter is a document being used to further your professional aspirations and should look like such. Your margins, font, font size, spacing, etc. should reflect that and relay to your potential employer that you take your job search seriously. Find a cover letter template structure you want to use and follow its layout when writing your own cover letter. 9. Sounding Desperate.  While of course you want to be hired, you dont want to come across as desperate for employment to companies. Do this by coming across as confident in both your abilities and their fit for the job you are applying for. Be concise and clear in your writing and while you dont want to hog the spotlight too much, you do want to make it clear in your cover letter that reading your  resume wouldnt be a waste of time and considering you for the position would be worthwhile as well. 10. Missing Information. Some of the most common cover letter mistakes are actually information left off of the cover letter. Failing to  include your contact information  or your signature could make the difference between getting a job offer or having your application end up in the rejected pile. Your cover letter and  resume could get separated so its imperative you include contact information, like your email address and phone number, on your cover letter. Search through the Uloop job listings to find your next Part-Time or Full-Time employment or Internship opportunity. Employers are waiting to hear from you!

Learning Chinese is Easy When You Have A Chinese Tutor

Learning Chinese is Easy When You Have A Chinese TutorFor those who are interested in the Chinese language, there is no doubt that the easiest way to learn the Chinese language is to hire a Chinese tutor in Bellevue. Language specialists can be found in any part of the world and will offer your personal assistance while you are learning Chinese. The basic reason why the Chinese language is so popular around the world is because it's one of the most beautiful languages in the world. There are millions of people who are learning the Chinese language every single day and this means that it's one of the few languages that are likely to become more common than English or Spanish over the coming years.Learning the Chinese language is not something that is an easy thing to do. In fact, learning this language can take a long time. That's why it's extremely important that you choose a tutor who is known for his proficiency and work experience in the field of Chinese language. It's a lot easie r to learn Chinese with a person who has studied the language extensively and knows a lot about it.Once you have a qualified teacher or expert, you need to be sure that you will get the level of instruction that you require. Whether you're having a very basic level of Mandarin, or you're having an advanced level of it, you must make sure that the instructor will help you achieve the level of learning that you are aiming for. By doing so, you will achieve the level of success that you wish to achieve.Teaching is a hard job, especially if you're teaching children. The language is different from others and most importantly, the syllabic system and word structure that are used are unique to Chinese.A great Chinese tutor will teach you how to speak, read and write Chinese with the aid of a computer program that can give you a good idea about the language. If you're trying to learn a variety of things including business skills, budgeting, and negotiation, then you may need a tutor who has worked in that particular area before. A good tutor will also be able to know where the right place to practice the language should be. And a good Chinese tutor will have experience in working with children as well.When you hire a tutor, make sure that you check out his background. You can find many on the internet who are willing to offer you their services. The best way to go about this is to contact your local chamber of commerce and see what other businesses there are in your area who are willing to offer this service.Tutors are available at most establishments in Bellevue and you can call them for more information.

What Should You Look For in an Online Chemistry Tutor?

What Should You Look For in an Online Chemistry Tutor?If you are going to earn your Ph.D., taking an online chemistry tutor can be a big help in getting all the classes and assignments taken for you and an insight into what to expect from the university in the long run. Unfortunately, a tutor is not one of the things that you will find as a part of most chemistry classes, so you must know exactly what to look for. Here are some of the key features that you will be looking for when hiring a tutor for your science course.- When it comes to being able to do research, an online chemistry tutor will give you the benefit of being able to check with a sample textbook or study guide, rather than having to do the work for yourself. They should be able to answer all your questions about how to go about working through each course, the syllabus and instructions, what to expect from labs and examinations, and any other questions you may have. They should also be able to answer all your concerns, such as when a deadline is due and who has priority in keeping a student's progress to a deadline. You should be able to consult with the tutors either in person or online, and the tutors should have online portfolios you can check out before enrolling. Remember, if the tutor is unable to meet the timetable that you set, then there is a possibility that you won't make it through the course.- The tutor should be able to offer advice and guidance to help you learn better, both as a student and a person. Your tutor should be open and honest, with his or her advice and guidance. They should be able to inform you of what they recommend for your learning and how it could improve your academic performance, as well as provide you with a list of resources for you to use.- The tutor should be willing to listen to you and understand what you want, and be able to help you get what you want. They should be able to suggest different courses of study and take the time to give you a complete revie w of your curriculum, so that you can know what to expect next. Remember, this is going to be a long term commitment for the tutor, so it is important that they are reliable and honest.- Your tutor should be willing to show you how to reach your goals by demonstrating your learning, rather than telling you about the different topics that you should study. They should be able to help you plan your study schedule, making sure that it takes the full hours for every class, not just a certain number of hours or an hour.- The tutor should be willing to come to the office, meet you at your home, or you can meet them at the institute. They should have an office they can be reached in and should be able to provide you with a phone number to call them for further help.These are just a few of the benefits of hiring an online IB Chemistry Tutor. There are many others, but this list should give you a general idea of the benefits of doing so.

How to Sequence a Yoga Class

How to Sequence a Yoga Class What is the Perfect Yoga Class Sequence? ChaptersSequencing a Power Yoga ClassHow to Sequence a Hatha Yoga ClassIdeal Sequencing for a Restorative Yoga ClassYin Yoga Sequences for Maximum BenefitsYoga is all about the mind-body connection; the asanas or poses, yoga breathing â€" breathing in tune with movement and meditation serve to foster that very connection.As yoga transcends the physical â€" indeed, it is the flow of energy that compels movement, would it matter in what order we do our salutations?Let us illustrate the point in a way that is easy to visualise.Let us suppose you want to get from Manchester to Edinburgh, maybe to attend a Yoga Alliance Professionals teacher training course. How would you get there?Would you first go across to Leeds and then up the A1 to Newcastle and then across to Edinburgh, or would you go up through Preston, follow the M5 through Carlisle until it turns into the A74, follow it into Glasgow and then cut across to Edinburgh?Would you fly or take a train there? Maybe, if you had your hea rt set on motoring, you could even hire a car to spare your own the miles.No matter what you decide, the end result is the same: you will arrive in Edinburgh. Does it matter how you get there?It does indeed! Environmentally conscious people might opt for the train while those in a hurry would probably fly. Those with a bit of time on their hands may consider a lengthy route through The Pennines a meditative opportunity.In that same vein, some people delight in the endless variety of asanas to be done in their Hatha yoga class while others love the rapid pace and endless vinyasas of power yoga.And if you need a break from all of those yang yogas, you could chill a bit with yin yoga.Virtually everything we do has a logical sequence: we walk before we can run, we are educated before we can seek out a career and we must have A before we can attain B.Why would yoga be any different?Today, your Superprof looks at four very different types of yoga, their merits and who they might be best s uited for, and how they should be sequenced.Got your yoga mat  rolled out and your yoga blocks handy?adho mukha svanasana (Downward-Facing Dog) and virabhadrasana (Warrior Pose), among others.Another trademark of a power yoga session is the fast pace. It is easy to see how this dynamic posture could easily lead into another pose Image by Wolfgang Eckert from PixabayPoses are attained but not held; generally, they flow into one another in concurrence with your breath. On that note, we should mention breathing…Certain breathing techniques are useful when practising yoga; for instance, deep breathing helps advance meditation. While doing power yoga, you will also breathe deeply.Power yoga consists of many asanas flowing into one another, separated by vinyasas.A vinyasa may consist of a Four-Limbed Staff pose (exhale), Upward Facing dog (inhale) and an exhale on the Downward Facing Dog.If you know even just rudiments of yoga poses, you’ll know that the Staff pose, also called the Low Plank fairly calls for an exhale as you tighten your core to get in position. Similarly, the up-dog opens the chest, demanding a deep inhale, which is then expelled when you move your head downward.From the moment you execute your first Sun Salutation until you fall in to savasana â€" the Corpse Pose at the end of your session, you will have cycled through close to 100 yoga poses.Granted, some of them are repetitions but still, that is a lot of asanas in one hour!To find out how they should be sequenced, enjoy our companion article.How to Sequence a Hatha Yoga ClassSome Hatha classes start with Sun Salutations; others leave that warmup off their sequence, maybe starting with a Mountain Pose and holding it for a few breaths before going into a Warrior Pose.Hatha is the Sanskrit word for 'force' but that doesn’t mean that Hatha yoga is a forceful discipline. Hatha is one of the yoga styles that permits going deep into a pose Image by StockSnap from PixabayIt flows at a slower pace than power yoga and permits plenty of time to go deeply into a pose.The philosophy behind Hatha yoga is to energise the body, opening up energy channels and focusing the mind, which ultimately permits meditation.Hatha classes generally start with standing poses, segue into hands-and-knees poses, flow into sitting poses and finally into poses in which you are laying down on your mat. It’s quite a logical flow!And, as there are, by some estimates, more than 5,000 yoga postures to choose from, you may ‘mix it up’ a bit, one day substituting a Tree pose for the Half Moon Crescent, or the Seal pose for the Cobra pose.Watch out, those two are very similar!The one pose to never do away with is the Corpse pose. Lying on your back, completely relaxed after your hourlong session is how you make the leap back into daily life.There truly is so much about Hatha yoga s essions that deserves mention, it merits its own, full-length article.Ideal Sequencing for a Restorative Yoga ClassPower yoga devotees and gym fanatics might walk past a yoga studio conducting a restorative yoga session and wonder why everyone is just lying there, by all appearances asleep. They may also wonder why that practice is called yoga.They may well be on the right track, wondering about restorative yoga, but not for those reasons.Generally speaking, yoga is meant to be invigorating yet restful; it is a way to unplug and restore yourself after constant brushes with stressors. So why are all of those people lying around, covered with blankets and barely moving?The point of restorative yoga is to cultivate stillness, a concept that is much harder than it sounds to achieve and maintain.Have you noticed how people today tend to walk around with earbuds stuck in, listening to something? Do you always have your ears plugged in?Granted, they (and you) might be listening to chanting , indulging in guided meditation while their bodies navigate the city streets or sit at their office cubicles… but what are the chances of that?The art of being still â€" the act of being completely motionless, without thoughts zinging through your head takes some cultivation.That lack of stillness that plagues so many of us can result in insomnia and stress-related diseases such as hypertension and even diabetes. Restorative yoga is a way to tune out the noise and get in touch with yourself once more.One fitness fanatic confided that he had become burnt out from his usual routine: a brisk jog in the morning followed by a day in the office, after which he repaired to the gym for a vigorous workout before heading home for a healthy dinner.He realised that his day was chock-full of movement with virtually no time to be still. And, while he lived a relatively healthy life, it nevertheless left him feeling vaguely unfulfilled.And then, he tried restorative yoga. Cultivating stillness is a way to reduce stress and centering your balance Image by engin akyurt from PixabayAll of the poses are done at floor level and your body is entirely supported for the duration of the pose, which can be up to 20 minutes. Best of all, restorative yoga incorporates what most aver is the ultimate inversion: the ‘legs up the wall’ pose!Don’t you think it is time for you to learn more about restorative yoga?Yin Yoga Sequences for Maximum BenefitsOur working life leaves us ripe for many types of injuries including repetitive motion injuries.A perfect case in point: sitting at a desk all day is not healthy; being sedentary causes all sorts of negative health consequences.If you have been stuck behind a desk for most of your working life, a yoga for beginners course might yet be too advanced for you.What you need to start with is a gentle yoga, one that will boost your flexibility without unduly taxing the joints and muscles you’ve not catered to in a while. Yin yoga fits that bill admirably.The entire sequence of poses is done at floor level and each asana (pose) is held for a couple of minutes.The idea behind yin yoga is to sit comfortably at the point of awareness; you don’t want to incur pain in your joints but you want to conscious of them â€" that they are opening up, releasing tension and gaining fluidity.While power yoga emphasises flowing from one asana to the next fairly rapidly, yin yoga gives you the chance to go deeper into each pose, to rediscover the carefree way of moving you enjoyed as a child.You won’t get to use as many pillows and blankets as you would in a restorative yoga class but you may use yoga blocks for support.Learn how, as well as the sequence of poses you might cycle through in your yin yoga class.Namaste!

Everything You Need to Know about the Properties of Waves.

Everything You Need to Know about the Properties of Waves. The Properties of Waves: Definitions, Amplitudes, and Oscillations. ChaptersWhat Defines a Wave?Longitudinal, Transverse, and Surface: What are the Different Types of Waves?What are the Different Parts of a Wave?Waves are everywhere. We hear with them, see with them, and they are present in all sorts of different materials and motions.When you drop a stone into a pool of water, those things that we commonly call ‘ripples’ are better described as waves. When we go to the beach, those big crashing piles of water â€" waves â€" are just a larger version of this usually microscopic physical phenomenon. When the wind rushes through trees or over fields, you are seeing waves there too.Here, we are going to be looking at the nature of waves as defined by physics. We are going to look at some of the features and terms â€" such as amplitude, wave propagation, frequency and wavelength â€" to discover what a wave really means to a physicist. And we’re going to look in greater detail at some of the important places in which we find waves in our world â€" fr om gravitational and electromagnetic waves to sound waves and water waves.Because this particular phenomenon is a really crucial part of our world to know. And as soon as you know how to identify a wave â€" and where you might find them â€" you’ll see them all over the place.So, let’s start looking at what a wave actually is. You can find an introduction to waves too.

What is a wave? (image from edraw)What you see is a fluctuating line that travels over and beneath a central point, in regular intervals. The distance between the highest points on the fluctuating line (or the ‘crests’) are regular, whilst the height and depth of the crests and troughs remain the same too. Without this regularity, you wouldn’t have a wave.A wave is a disturbance or variation in space-time that is accompanied by a transfer in energy. This is the definition that you will need to remember. If you imagine that, in an ideal world, a normal wave line would be completely flat â€" with no wave at all â€" what you see on the diagram is a transfer of energy that is the disturbance.Of course, this isn’t a reality that we ever witness. Energy is always being transferred â€" and, as such, there are always waves present, in much more complex variations and interferences than any diagram could possibly show.Mechanical Waves and Electromagnetic Waves.Before we go on to tackl e the shapes and movements of different waves, it is important to recognise two prior types of waves. Because maybe you have heard of electromagnetic waves â€" which are light waves by the way. These function in a slightly different way to the waves in our diagram above.Mechanical Waves.Mechanical waves are the waves that we recognise all around us. These are the ocean waves and the ripples of water, the sound waves with which we hear, and the seismic waves that destroy buildings and rupture the earth in an earthquake.These mechanical waves need a medium through which to travel â€" as in, some sort of matter. In these guys, energy is moved across particles.Imagine an earthquake. Here, an initial force causes disturbances across the matter of the earth. This force can travel so far â€" as in, damage can be done hundreds of miles from the epicentre â€" because the waves can travel through all the matter of the earth, transporting kinetic energy for huge distances.Without the earth’s substance â€" or if, say, for some reason, the seismic waves encountered a vacuum â€" the earthquake could not possibly pass through.Electromagnetic Waves.Whilst mechanical waves need a medium to disturb in order to transfer energy, electromagnetic waves do not. These, such as light waves, can propagate even across a vacuum. And this fact is a little bit problematic for our understanding of waves per se.You’ve probably heard of the famous scientific problem that states that light is both a wave and a particle (you may well have heard of Schrodinger’s Cat) â€" that, depending on how you try to observe it, light behaves both like a particle and like a wave. This is one of the complex things about it.Electromagnetic waves like light are produced by the interaction of a magnetic field and an electric field. Changes to one of these produces changes in the other â€" and at the same time produces electromagnetic waves.Alongside light, radio waves are another type of electromagnetic wa ve.Find a physics and maths tutor s1 here. Rendering of a sound waveWaves and Energy Transfer.Having clarified this, let’s pin down the most important â€" and useful â€" part of the nature and structure of waves. This is the fact that they transfer energy.In waves, it is energy that is transferred. Whilst the particles or matter through which the waves pass briefly moves, the net movement of material is zero: the particles return to their original position after the wave has passed on.Remember: energy, not matter, is transferred by waves.Longitudinal, Transverse, and Surface: What are the Different Types of Waves?Alongside these two fundamental types of waves, there are different categorisations that describe the type of movements that the waves make. These categories describe the ways in which particles are displaced by the wave â€" and the different materials through which the wave propagates.Longitudinal Waves.We describe waves as longitudinal if they have particles that move parallel to the movement of energy in the wav e. Rather than the crests and troughs that we see in the classic wave diagram, longitudinal waves do not have this up-down motion.This, in scientific terms, is expressed differently. They do not demonstrate polarization â€" i.e. they don’t have the peaks and troughs â€" but rather their oscillation is in the direction of the energy’s travel.Sound waves are an example of this sort of wave â€" and they can move through solids, liquids, and gases.Transverse Waves.A transverse wave is the type of wave that we see in our familiar wave diagram. Here, the movement of particles is at right angles â€" it is perpendicular â€" to the movement of energy.A transverse wave demonstrates the wave polarization that a longitudinal wave would lack: they have that clear movement between peak and trough. This polarisation, by the way, is measured in amplitude, which describes the distance between the peaks and the centre of the wave.These are the easiest waves to study because you can easily see the polarisation and the wavelength â€" or the distance of an oscillation (the time it takes for a wave to repeat itself).Imagine a rope or a slinky that you raise and lower rapidly. Across the length of the rope you will see a peak travelling along the length of the rope. This is a transverse wave.Surface Waves.In surface waves, particles travel in a circular motion spreading out from the originary disturbance. These are actually a combination of transverse and longitudinal waves that play along the interface between different media.You’ll know these types of waves: drop a stone in a pool of water and every ripple that you will see is a surface wave. Their circular motion comes from this combination of transverse and longitudinal.Find out more about transverse and longitudinal waves! Sea waves work on the same principles as sound.What are the Different Parts of a Wave?Let’s do a little recap of the most important parts of the wave that we have so far discussed. If you are reading this article to help with school work, it is important that you know all of these terms very well.So, here are the most important parts of a wave.Rest position â€" This is the position of particles when there is no energy or wave passing through them; these particles are undisturbed. On a wave diagram, this is the line that is drawn through the centre of the wave.Displacement â€" This is the distance that a particle has moved from its rest position due to its disturbance.Amplitude â€" The measurement of displacement, we call the amplitude the maximum disturbance of a particular point in the medium. This is the distance between the rest position and the highest peak or trough.Peaks and troughs â€" The points of greatest disturbance or maximum displacement, above and below the rest posit ion.Oscillation â€" The repetition of a wave â€" i.e. the space from peak to peak.Wavelength â€" The actual distance covered by one oscillation â€" usually measured from peak to peak.Frequency or wave speed â€" The number of times a wave oscillates in a second.Find out about reflection and refraction - or about sound waves!
