Physics - Sound Wave Question with Solution | TestHub

Consider the sound wave travelling in ideal gases of $\mathrm{He},{\mathrm{CH}}_4$, and ${\mathrm{CO}}_2$. All the gases have the same ratio $\frac{P}{\rho }$, where $P$ is the pressure and $\rho$ is the density. The ratio of the speed of sound through the gases ${\mathrm{v}}_{\mathrm{He}}:{\mathrm{v}}_{{\mathrm{CH}}_4}:{\mathrm{v}}_{{\mathrm{CO}}_2}$ is given by
