Marquez is in the ocean on his surfboard. While waiting for the perfect ride, he notices that waves pass him about every 4 s. What is the frequency of the waves?

A. 0.75 Hz

B. 0.5 Hz

C. 0.25 Hz

D. 0.2 Hz

1 wave/4s = ?

A. 0.75 Hz

To find the frequency of the waves, we need to use the formula:

Frequency = 1 / Time period

The time period is the time it takes for one complete wave to pass by. In this case, the waves take 4 seconds to pass by Marquez.

So, the frequency can be calculated as:

Frequency = 1 / 4 s

Simplifying the equation, we get:

Frequency = 0.25 Hz

Therefore, the correct answer is C. 0.25 Hz.
