Q. Velocity of sound in a gaseous medium is $330 \,m \,s ^{-1 .}$ If the pressure is increased by $4$ times without change in temperature, the velocity of sound in the gas is

Waves

Solution:

Velocity of sound in gas, $v=\sqrt{\frac{\gamma P}{\rho}}=\sqrt{\frac{\gamma R T}{M}}$
Pressure has no effect on velocity of sound in a gas as long as temperature remains constant.
