14. What is the frequency of the wave?
(a) 0.67 Hz (c) 13 Hz (e) 57 Hz
(b) 1.33 Hz (d) 30 Hz

15. What is the shortest horizontal distance from a crest to a point of zero acceleration?
(a) 0.38 m (c) 1.5 m (e) 6.0 m
(b) 0.75 m (d) 3.0 m

16. How long does it take a particle at the top of a crest to reach the bottom of an adjacent trough?
(a) 0.018 s (c) 0.075 s (e) 0.30 s
(b) 0.038 s (d) 0.150 s
