When pressure on a gaseous medium is changed at constnat temperature, what will be effect on the speed of sound wave in it ?

Explanation

Speed of sound wave in a gaseous medium is,
`v = sqrt ((gamma P )/(rho))`
`therefore v = sqrt ((gamma P )/(M //V)) = sqrt (( gamma P V )/(M )) = sqrt ((gamma mu RT)/( mu M _(0))) = sqrt (( gamma RT)/(M _(0)))`
`therefore ` At constant temperature, `v=` constant
`thereofre ` At constant temperaure, there will not be any effect of change in pressure on the velocity of sound wave in it.
