Question

as you sit on a dock, you notice a wave crest pass. you count another 16 wave crests in the next eight seconds. what is the frequency of these waves?

Answer 1

2 Hz

Step-by-step explanation:

The frequency of a wave is the number of complete oscillations in one second. It can also be calculate as the number of crests that pass on a given point in one second.

In this case, you count 16 waves that pass the given point in 8 seconds. Therefore, the frequency will be the number of waves divided by the time taken:

`f=(N)/(t)=(16)/(8 s)=2 Hz`

Answer 2

The SI unit for frequency is Hertz (Hz), or simply, the reciprocal of a second. It measures how fast an object could be moving. In this case, the frequency would be 16 wave crests per 8 seconds (16/8 = 2). In simplified answer, the frequency is 2 per second, or 2 Hz.
