Q.

How does (c) produce both types of wave? And in stationary wave why does amplitude differ from one particle to another, but not in case of progressive wave?

Given below are some examples of wave motion. State in each case if the wave motion is transverse, longitudinal or a combination of both :

(a) Motion of a kink in a longitudinal spring produced by displacing one end of the spring sideways.

(b) Waves produced in a cylinder containing a liquid by moving its piston back and forth.

(c) Waves produced by a motorboat sailing in water.

(d) Ultrasonic waves in air produced by a vibrating quartz crystal.
