Refraction occurs for both sound and light. When refraction occurs there is a change in
1) frequency.
2) wavelength.
3) speed.
4) all of the above.
When sound travels faster near the ground than above, bending of sound tends to be
5) upward.
6) downward.
7) neither of these.
Question 2
A V-shaped bow wave is produced when a boat moves

2) as fast as the waves in the water.
3) faster than the velocity of waves in the water.
4) at any speed, slower or faster than the water waves.
Which bow wave corresponds to the faster-moving boat?
5) I
6) II
