Question

We can polarize light wave. Then can we polarize the sound wave? If no pls tell the reason? If yes pls tell how to polarize sound wave?

Answer 1

Quite generally, to have polarized waves, they first need to be transverse waves - the disturbance needs to be at right angles to the direction of propagation. Then since in 3D you have one direction of propagation and two directions at right angles to it, you can have two polarizations.

Answer 2

Explanation:

The law stating that if the direction of a light beam is reversed, despite the number of times the beam is reflected or refracted, it will follow the same path.
