Question

Consider the sound wave travelling in ideal gases of ${\rm{He}},{\rm{C}}{{\rm{H}}_4}$, and ${\rm{C}}{{\rm{O}}_2}$. 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 ${{\rm{V}}_{{\rm{He}}}}:{{\rm{V}}_{{\rm{C}}{{\rm{H}}_4}}}:{{\rm{V}}_{{\rm{C}}{{\rm{O}}_2}}}$ is given by

Select the correct option:

$\sqrt {\frac{7}{5}} :\sqrt {\frac{5}{3}} :\sqrt {\frac{4}{3}} $

$\sqrt {\frac{4}{3}} :\sqrt {\frac{5}{3}} :\sqrt {\frac{7}{5}} $

$\sqrt {\frac{5}{3}} :\sqrt {\frac{4}{3}} :\sqrt {\frac{4}{3}} $

$\sqrt {\frac{5}{3}} :\sqrt {\frac{4}{3}} :\sqrt {\frac{7}{5}} $
