frequency determine the frequency (in hz) by counting the number of waves per second... time in seconds frequency hz # of waves per second
Answer
Explanation:
Step1: Count waves in 2 - second
Count the number of waves from 0 to 2 seconds. There are 10 waves.
Step2: Calculate frequency
Frequency $f=\frac{\text{Number of waves}}{\text{Time}}$. Here, time $t = 2$ s and number of waves $n=10$. So $f=\frac{10}{2}=5$ Hz.
Answer:
5 Hz
