Q. When longitudinal wave propagates, what happens in the region of compressions and rarefactions?
J & K CET
J & K CET 2014
Waves
A
Density varies
56%
B
Density remains constant
22%
C
There is heat transfers
14%
D
Boyle's law is obeyed
8%
Solution:
In compression region density increases and in rarefaction density decreases. So, density varies due to sound propagation.
