Chapter 16 Wave Motion

If you lower the frequency of a wave in a string you will

	lower its speed.
	increase its wavelength.
	lower its amplitude.
	shorten its period.

A wave pulse is moving, as illustrated with constant speed v along a rope. Which of the graphs correctly illustrates the relation between the displacement y of point P and time t.

A periodic wave is made to travel from a thick string into a thin string held at the same tension.

As the wave passes the join the wave's

	frequency increases.
	frequency decreases.
	wavelength increases.
	wavelength decreases.
