- Homework Statement
- A rope RS has a pulse at ##t=0## traveling towards the right at ##1 m/s## as shown in the first diagram below.

What will be the direction of motion of points A, B and C at ##t=0##?

- Relevant Equations
- None

The second diagram is my attempt at the solution, in which the dotted part is the pulse in the rope a very small interval of time after ##t=0##.

Point A should be at rest since we know wave is moving towards right and point A on the rope becomes a part of initial horizontal part of the string a moment after ##t=0##.

I am still trying to figure out the reasoning behind the direction of motion of points B and C.
