Sound wave is travellimg along positive x -direction . Displacement (y) of particles from their mean position at position x is a shown in figure . Choose the correct alternative(s).

A

Particle located at E has its velocity in positive

B

Particle located at D has zero velocity

C

Particles located near C are under compression

D

Change in pressure at D is zero

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
Particle located at point D is maximum displaced, so it has zero velocity at the givenn instant.
