Sound waves are travelling in a medium whose adiabatic elasticity is \( \mathrm{E} \) and isothermal elasticity \( \mathrm{E}^{\prime} \). The velocity of sound waves is proportional to
(a) \( \mathrm{E} \)
(b) \( \sqrt{\mathrm{E}} \)
(c) \( \sqrt{\mathrm{E}^{\prime}} \)
(d) \( \frac{E}{E^{\prime}} \)
