Question

Velocity of sound is directly proportional to the _________ of the medium
​

Answer 1

Answer:

This implies that speed of sound must be proportional to density of the medium. But in the expression v=sqrt (gP/r) speed of sound 'v' is inversely proportional to the density 'r' of the medium, and directly proportional to 'g'(gamma) and pressure. Therefore,speed of the sound is inversely proportional to density.
