A transeverse wave is propagating in a string in which a tension is maintained. A, B, C and D are four particles of the string.
Then select the correct option.

Moderate

A

When the wave is propagating from right to left. Velocity vectors of A and B are downward and velocity vectors of C and D are upward.
B

When the wave is propagating from right to left velocity vectors of A and C are upward and those of B and D are downward.
C

When the wave is propagating from left to right, velocity vectors of A and B are upward and velocity vectors of C and D are downward.
D

When the wave is propagating from left to right, velocity vectors of A and C are upward and those of B and D are downward.

Solution

When direction of propagation is from right to left, crest and trough should move to the left and for this to be satisfied particles A and B should move downward and particles C and D should move in upward direction.
