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