Question

. Answer
(a) Is there a permanent displacement of medium particles in a wave motion
6) How is direction of vibration of medium particles related to direction of propagation of
a longitudinal wave?
(c) Which characteristic of sound depends on its amplitude?​

Answer 1

Explanation:

(a) No. there is no permanent displacement of particles in propagation of a wave motion

(b) In longitudinal waves, the particle of medium vibrates parallel to the direction of propagation of wave.

(c) Loudness of sound depends on its Amplitude
