The ratio of the velocity of sound in hydrogen gas to helium gas at room temperature if their 
are 
and 
respectively.
Text Solution
Verified by ExpertsThe correct answer is:
A
From Newton-Laplace equation, we know that speed of sound in a gas is given as
Here we observe that R and T are same and equal for both the gases. As a result they will cancel out when we take the ratio of speeds of sound in these two gases as follows:-
