The drawing shows a snapshot of a transverse wave moving to the left on a string. The wave speed is 10.0 m/s. At the instant the snapshot is taken,
(a) in what direction is A moving?
(b) In what direction is point B moving?
(c) At which of these points is the speed of the string segment (not the wave speed) larger? Explain.
(d) How do your answers change if the wave moves to the right instead?
