Web6. The formula for finding the velocity of a longitudinal wave, such as a sound wave, is: v = E ρ. Where v represents the velocity, E represents the elasticity of the medium, and ρ represents the density of the medium. From this formula, it is obvious that velocity is inversely proportional to the square root of the density of the medium.
