ARE YOU JUST NOW MEETING ME CAUSE WE ARE LEARNING HOW TO WAVE! Or about waves.

        Oh, Hello People of the Earth! *waves an annoying wave* *only some people will get why that's funny* If you looked at the title you can realize that I am teaching you about waves! Well, not the greeting.... The actual scientific wave...

        So, as you can see that is adorable but we aren't learning about them or that kind of wave, we are learning about the wave that actually has to do with science. So, do you know what waves are? Well, I don't care if you do or don't I'm telling you! :D Waves are chains or vibrating molecules. They transfer energy from one place to the another. When you are talking, you are making a sound, which is a type if wave. Earthquakes are a type of wave because it transfers energy. There are many more examples, but there are too many to list.

 

        Scientists broke waves into two basic groups, mechanical and electromagnetic. Mechanical waves are waves that need a medium to move through. A medium is any kind of matter that's disturbed by energy. The energy disperses through the medium in the form of waves. There are two different types of mechanical waves, transverse and compressional. I know, it might be confusing but bare with me. If it's not confusing, then good for you!

        Transverse waves are waves that carry energy by making it move at right angles to direction of the energy flow. Compressional waves, aka longitudinal waves, displace matter back and forth in the same direction as the energy of the wave. When the compressing air molecules hit your eardrum, it causes a vibration. When that happens, it sends sound signals to your brain. Cool, huh! These two waves are similar because they are both mechanical waves, and they both transfer energy. They are different in the ways they travel, though.

        Okay, so the two main types of waves in general are mechanical and electromagnetic. Then, there are two other groups that fall under mechanical, compressional/longitudinal and transverse. Okay, hopefully you got that. If you didn't, sorry I have to move on. Look for more information here! That's where I got mine from. Okay, let's talk about electromagnetic waves now. Electromagnetic waves are waves that don't need a medium to move through. They can travel through empty space. This is why you can see outside! Isn't that nice! The light waves from the sun can travel through empty space and reach Earth. Cool, right?

 

        Okay, because its pretty late right now and I don't want to write out a huge long paragraph that would be to long to read, I'm going to write out a couple bullet points describing the different parts of a wave. *If anyone says this is a copied idea, I actually wanted to do this before I heard of anyone else is doing it!*

• Crest: the highest point of a traverse wave
• Trough: the lowest point of a traverse wave
• Amplitude: the distance between the midpoint of aware and the crest
• Wavelength: the length between a crest and a crest, or trough to trough 
• Frequency: the number of waves that pas a given point in one second. If you have high frequency, that means that you have taller waves, and a shorter wavelength. If you have low frequency, that means that you have wider waves, and a longer wavelength. 
• Fun fact! Frequency is measured by hertz (waves per second).

        WELL THAT'S ALL FOR TODAY! BYEEEEE!

Please tell me your feedback! I'd like 
to know how I did! I would love to 
know what you thought of this! 
Thanks for reading everyone! <3 :D
