Question

Problem 12

Answer 1

Given information

Given:

When a wave on a string is moving to the right, we need to find the direction of velocity of a particle of string at point B.

Step-by-step explanation

Step 1.

Here we know that the points cannot move horizontally while, velocity is zero only on turning points.

And from the graph we can observe that, the wave is moving towards right, so the crest is approaching point B upwards.
