Velocity

Vedclass · Answer

(C) The velocity of sound in a gas is given by the formula $v = \sqrt{\frac{\gamma RT}{M}}$,where $\gamma$ is the adiabatic index,$R$ is the universal gas constant,$T$ is the absolute temperature,and $M$ is the molar mass of the gas.From this relation,it is clear that $v \propto \sqrt{T}$.Therefore,when the temperature of the atmosphere increases,the velocity of the sound wave increases.

If the temperature of the atmosphere is increased,which of the following characteristics of a sound wave is affected?
