A sound wave is passing through air column in the form of compression and rerefactions. In consecutive compressions and rerefactions.

A

density remains constant

B

Boyle's law is obeyed

C

bulk modulus of air oscillates

D

there is no transfer of heat

Text Solution

Verified by Experts

The correct Answer is:
D
There is no transfer of heat from compression to rarefaction as air is a bad conductor of heat. And time of compression`//` rarefaction is too small.

Compression and rarefactions are formed in ______

Assertion : Sound waves travel in the form of compressions and rarefactions in air. Reason : Because crests and troughs cannot be sustained in air, therefore, sound waves cannot travel through air in the form of transverse waves.

How are compressions and rarefactions produced near a source of sound ?
