As you sit on a dock, you notice a wave crest pass. You count another 10 wave crests in the next 15 seconds. What is the frequency of these waves?
A. 10 Hz
B. 15 HZ
C. 0.667 Hz
D. 1.5 Hz

Frequency of the waves = 0.667 Hz

Explanation:

Given:

Number of waves = 10

Time taken = 15 seconds

Find:

Frequency of the waves.

Computation:

⇒ Frequency of the waves = Number of waves / Time taken

⇒ Frequency of the waves = 10 / 15

⇒ Frequency of the waves = 0.667 Hz
