Question

Define the terms velocity and wavelength applied to sound wave and state the relation between velocity, frequency and wavelength.

Answer 1

Wave- velocity: It is the velocity with which a wave propagates in a particular medium.

Wavelength: The wavelength is the distance between two successive crests or two successive troughs on a transverse wave.
It is also equal to the distance between any two points where the particles are passing through their respective mean positions in the same direction.
It is also the distance between two successive compressions or two successive rarefactions on a longitudinal wave.

Wave-velocity = wavelength x frequency
