A pulse travelling to + x is drawn on a string (Figure 6.96): points A and E lie on the flat baseline, B on the rising front, C at the crest and D on the falling back. Which points are instantaneously

Question

A pulse travelling to + x is drawn on a string (Figure 6.96): points A and E lie on the flat baseline, B on the rising front, C at the crest and D on the falling back. Which points are instantaneously at rest, and do your answers depend on direction of propagation?

TestHub · Accepted Answer

Particle velocity is − v ∂ y / ∂ x for a wave moving to + x . It is zero where the slope is zero: A , C , E . B (positive slope) moves down and D (negative slope) moves up; reversing the direction reverses these two.
