Explain with an example, the propagation of sound in a medium.

State three characteristics of the medium required for the propagation of sound in a medium.

During the propagation of e.m. wave in a medium

A stationary source sends forth monochromatic sound. A wall approaches it with velocity 33 cm/s. The propagation velocity of sound in the medium is c=330(m)/(s) . How much, in per cent , does the wavelength of sound change on reflection from the wall?

(a) State and explain Newton's formula for the velocity of sound in the medium. (b) How is modified to find the velocity of soun in gas ?

Write the difference between the propagation of sound and light waves.
