Velocity of sound wave

For the propagation of the waves, through the medium, there are 2 important factors affecting the velocity of waves in the medium.

  1. Elastic factor i.e. modulus of the elasticity of the medium.
  2. Inertial force i.e. density of medium

Velocity of sound wave

Which can be proved in the medium depends upon the modulus of elasticity and density of medium.

Velocity of sound wave

Hence proved.
