Physics - Sound Wave Question with Solution | TestHub

$v=\sqrt{\frac{\gamma RT}{M}}=\sqrt{\frac{\gamma P}{\rho }}$ (i) Velocity of sound is proportional to $\sqrt{T}$ $\therefore$ $v\propto \sqrt{T}$ (ii) When $\rho$ is constant, the velocity of sound is proportional to root of pressure $P$ $\therefore$ $$v\propto \sqrt{P}$$
