A transverse wave is travelling along a string from left to right. The figure below represents the shape of the string at a given instant. At this instant the points have an upward velocity are (here X-wave displacement, Y- particle displacement)

A

`D,E,F`

B

`A,B,H`

C

`B,D,F`

D

`A,E,H`

Text Solution

Verified by Experts

The correct Answer is:
A
At `D,E,F` slopes are negative so velocities are positive
