A) \[1:2\]
B) \[4:1\]
C) \[2:1\]
D) \[1:4\]
Correct Answer: C
Solution :
Relation for the velocity of sound is \[\upsilon =\sqrt{\gamma \frac{P}{\rho }}\] hence \[\frac{{{\upsilon }_{1}}}{{{\upsilon }_{2}}}=\sqrt{\frac{{{P}_{1}}}{{{\rho }_{1}}}\times \frac{{{\rho }_{2}}}{{{P}_{2}}}}=\sqrt{\frac{4}{1}}=2:1\]You need to login to perform this action.
