Question #64d80

Dec 16, 2017

There are two types of wave, but all transfer energy (or information) from source to detector.

Explanation:

You could also say they are all repeated periodic oscillations in an elastic medium (so the particles in the medium do not translate, only oscillate), they all obey the wave equation ($v = f \times \lambda$) and all (I think all) decrease in intensity with distance squared.
