The bird at the right watches the waves. If the portion of a wave between 2 crests passes the pole each second.

(a) What is the speed of the wave?

(b) What is its period?

Suppose that the distance between crests in the above question were 1.5 meters apart and 2 crests pass the pole each second.

When an automobile moves toward a listener, the sound of its horn seems

relatively louder at a higher frequency
relatively softer at a higher frequency
relatively louder at a lower frequency
relatively softer at a lower frequency

and when moving away from the listener, its horn seems

relatively louder at a higher frequency
relatively softer at a higher frequency
relatively louder at a lower frequency
relatively softer at a lower frequency
