Question

The velocity of sound produced by a vibrating body varies ___________.

• A. inversely as the frequency of the medium
• B. inversely as the density of the medium
• C. directly as the square root of density of the medium
• D. directly as the square root of frequency of the medium

Answer 1

The correct option is B inversely as the density of the medium

Velocity of sound varies inversely to density of medium and directly to elasticity of medium.

$v=\sqrt{\frac{Elasticitycoefficient}{density}}$
