During the propagation of a longitudinal wave, in the region of compressions and rarefactions
- A density varies
- B density remains constant
- C there is heat transfer
- D Boyle's law is obeyed
Answer & Solution
Correct Answer
(A) density varies
Step-by-step Solution
Detailed explanation
When a longitudinal wave propagates through solid liquid or gas then the particles of medium start oscillating about there mean position up and down in the same direction in which the wave travels. At any instant there are point in space where density is height called…
