Waves and Their Properties

Ever noticed how a leaf floating on a pond just bobs up and down when waves pass by, rather than getting swept away? That's because waves transfer energy, not matter - one of the most important things to remember about wave behaviour.

Waves are vibrations that carry energy from one place to another without moving the actual material. Think of a Mexican wave in a football stadium - the wave moves around the stadium, but each person stays in their seat. The amplitude is the maximum height of a wave from its resting position, whilst the wavelength is the distance between two identical points on neighbouring waves.

You'll need to know about frequency too - this measures how many complete waves pass a point each second, measured in hertz (Hz). The period is simply how long one complete wave takes to pass by. These concepts link together in wave equations you'll use in calculations.

Transverse waves oscillate perpendicular to their direction of travel (like waves on water), whilst longitudinal waves vibrate parallel to their direction (like sound waves). Longitudinal waves have compressions (squeezed areas) and rarefactions (stretched areas) instead of peaks and troughs.

Quick Check: Sound waves making a candle flicker and a slinky spring bouncing are perfect examples of energy transfer without matter movement - the candle stays put, and the slinky doesn't travel down the room!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
