Two monatomic ideal gas 1 and 2 of molecular masses `m_(1) and m_(2)` respectively are enclosed in separate containers kept at same temperature. The ratio of the speed of sound in gas 1 to that in gas 2 is given by

A

`sqrt((m_(1))/(m_(2)))`

B

`sqrt((m_(2))/(m_(1)))`

C

`(m_(1))/(m_(2))`

D

`(m_(2))/(m_(1))`

Text Solution

Verified by Experts

The correct Answer is:
B
`V_("sound") = sqrt((gammaRT)/(M_(W))) "so" (v_(1))/(v_(2)) = sqrt((m_(2))/(m_(1)))`
