###### Question:

Waves
The figure shows a 2em-wide (non-dispersive) wave pulse traveling to the right with speed 2cm/s. At the instant shown the pulse's peak is at x-2em. At this instant, are any segments of the string moving to the right? (Convince yourself no!!) Which segments of the string are moving up? Which are moving down? Is there any segment of the string (beside the flat sections) that is momentarily at rest? 1) v 2 cm/s X (in em) Hint: Sketch the pulse at its starting position and also draw where it will be an instant later, then compare
