If `v_(m)` is the velocity of sound in moist air, `v_(d)` is the velocity of sound in dry air, under identical conditions of pressure and temperature

Options

A. `v_(m) lt v_d`
B. `v_(m) gt v_(d)`
C. `v_(m)v_(d)=1`
D. `v_(m)=1v_(d)`

Answer

B

Explanation

Velocity of sound in air
`v=sqrt((gammaP)/(d))`.
Since moist air is lighter than dry air, `v_(m) gt v_(d)`.
