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.
