A transverse wave is travelling along a string in the positive x-axis. The

shows the photograph of the wave at an instant. Find
(a) the points moving upwards
(b) the points moving downwards
(c ) the points which have zero velocity
(d) the points which have maximum velocity

Text Solution

Verified by Experts

The correct Answer is:
(a) `D, E, F` , (b) `A, B, H` , (c) `C, G` , (d) `A, E`
(a) `D, E, F rArr` (slope `= -ve rArr v_(p) = +ve`)
(b) `A, B, H rArr` (slope `= +ve rArr v_(p) = -ve`)
(c) At `C, G`, [slope `=0`]
(d) At `A, E` [slope is maximum]
