Question

a) What are the two different types of waves?

b) How do these waves differ?

c) What type of wave are sound waves?

Answer 1

wave is a a disturbance or variation that transfers energy progressively from point to point in a medium
A
Two types of waves:

Stationary and transverse wave.

B-

Transverse wave in which motion of particles is in prepndicular direction to the direction of propagation of wave. e.g. - string wave, light wave.

Longitudinal wave in which direction of motion of particles is in the same direction of propagation of wave. Eg. - sound wave.

C-

Hence longitudinal waves are sound wave.
