When you define longitudinal, you should have the graphics correspond with the actual definition and the actual reality of the motion. If you are teaching how it works, you need to show how it works, not -something sort of like it. - You say that with a longitudinal wave, the wave travels in the same direction as the line. but you show a coil with a wave going left to right. That's not how sound works. It does not go back and forth along the longitudinal line, it goes in one direction. The perpendicular motion is the only oscillation. The wave goes in one direction, and your graphics should show that, not the mess you're using trying to make a Slinky wiggle. This is only going to cause confusion for your viewers. Show the actual physical motion, not a distorted -cute- image that conflicts with the verbal description.

I just feel this diagram is talking of amplitude whereas speaker is replacing the word with frequency. Now I'm confused to understand if frequency corresponds to amplitude or amplitude corresponds to frequency or vice versa or they are synonymous in use! Some expert, Help me

5: 06 gosh, I served in US air base where air planes and fighter jets frequently take off and land. That really did drive me round the bend. Miraculously, I managed to retain my hearing. Cheers for the instructive lecture and reminding me of that memory mate!

Dear,
Crash Course,
I am wondering what is the name of the song they used for the H3 Ethan reference. I want to get that sound file for my mp3 player. It sounds nice even in this episode. Keep up the wonderful work crash course.

Did I miss this somewhere? What's the amplitude of a longitudinal wave? Is it how big or wide the pressure wave is? XD
I have no idea, please someone explain this.

It-s been a while since I-ve been following your videos, and I must say, they are amazing! By any chance, is there a scope for business collaboration?
