Which of the following statements are correct?

A

Changes inair temperature have no effect on the speed of sound.

B

Changes in air pressure have no effect on the speed of sound.

C

The speed of sound in water is higher that in air.

D

The speed of sound in water is lower than in air.

Text Solution

Verified by Experts

The correct Answer is:
B, C
`v=sqrt((gammaRT)/(M))`
Change in temperature affects the velocity of sound is air but as long as temperature remains same change in pressure has no effect.
`v=sqrt((B)/(P))`
Bulk modulus of water is very high, so velocity of sound in water is higher than that in air.
