How exactly do waves travel through materials?

Question

Physics

Hello!
I am looking for visual materials in order to study this topic, preferably in pictures or videos. Thanks

Answer 1

I can’t give a good example, and I can’t imagine it myself 100%, but everything is tied to the wavelength that passes through the body. It would be better to ask how waves do not pass through bodies? After all, as we know, all the bodies around are essentially 99.999 ...% of emptiness, this is due to the large distances between atoms compared to the size of the atoms themselves. And for waves there is no difference between the space between bodies and in them ... Unless, of course, these are waves with a small wavelength, commensurate with the distances between atoms. In this case, the charges that are in the body are perturbed by this very wave and create their own electromagnetic fields, which "interfere" with the propagation of the original one. I hope I didn't misrepresent the essence of things.

Answer 2

Sound, electromagnetic, gravitational (new) ?
