Question

Observe the following sound waves and write any two differences between them.​

Answer 1

There are two basic types of wave, transverse and longitudinal, differentiated by the way in which the wave is propagated. ... Sound propagates through air or other mediums as a longitudinal wave, in which the mechanical vibration constituting the wave occurs along the direction of propagation of the wave.

Answer 2

First Wave(above one)-

$\implies$The wave is non-uniform and amplitude vary.

$\implies$The frequency of the wave is more.

Second Wave(below one)-

$\implies$ The wave is uniform and amplitude is constant.

$\implies$The frequency of the wave is less.
