Waves

Hey guys, I'm back and today I'll be talking about waves, but not just one type of wave, I'll be talking about almost all of them. I'll talking about electromagnetic waves, seismic waves, sound waves, mechanical waves, transverse waves, and compressional waves. Waves carry energy and not matter.

 

The amplitude of a wave is the amount of vibration inside of that wave. The difference between a electromagnetic wave and mechanical wave is that mechanical waves need a medium to carry their energy through, while electromagnetic waves can basically travel through empty space. How do you think sun rays get to Earth.





There are two different type of mechanical waves. Transverse and Compressional waves. Compressional waves compact together, while Transverse waves move in a right angle. To make a sound wave you have to make an object vibrate, an exaxmple is hitting a metal spoon against a metal railing.

The crest of a wave is the top of a wave, the trough of a wave is the bottom of a wave, amplitude is the maximum amount of a vibration in a wave, wavelength is measured from crest to crest and also from trough to trough, and frequency is the number of waves past a certain point per second.

                       That's all for today guys see ya next time.
