Question

When longitudinal wave propagates, what happens in the region of compressions and rarefactions? (A) Density varies (B) Density remains constant (C) There is heat transfers (D) Boyle's law is obeyed

In compression region density increases and in rarefaction density decreases. So, density varies due to sound propagation.

Q. When longitudinal wave propagates, what happens in the region of compressions and rarefactions?

Density varies

Density remains constant

There is heat transfers

Boyle's law is obeyed

In compression region density increases and in rarefaction density decreases. So, density varies due to sound propagation.
