what is the frequency of this wave?\n1\n2\n3\n4\n1 second

Answer:

4

Explanation:

Step1: Recall frequency formula

Frequency = $\frac{\text{Number of cycles}}{\text{Time}}$

Step2: Count cycles in 1 second

There are 4 complete cycles in 1 second.

Step3: Calculate frequency

Frequency = $\frac{4}{1}=4$
