Question

directions: answer the question about frequency.
a wave completes 20 wave cycles in one second. what is the frequency of the wave?
hz

Explanation:

Step1: Recall frequency definition

Frequency ($f$) is the number of cycles per unit time. The formula is $f=\frac{\text{Number of cycles}}{\text{Time}}$.

Step2: Substitute values

Number of cycles = 20, Time = 1 second. So $f = \frac{20}{1}=20$ Hz.

Answer:

20
