You are at the beach, counting the waves as they hit the shore. In 2 minutes you count 15 waves. What is the period and frequency of these waves?

The period and frequency of these waves are 8 s and respectively

Explanation:

Period is defined as the time taken per wave cycle.

Total time duration = 2 minutes = 120 sec   (1min = 60 sec)

Number of waves = 15

Hence, period or time duration per wave =

Frequency is defined as the number of waves passing per unit time.

number of waves in 120 seconds = 15

number of waves in 1 seconds =

The period and frequency of these waves are 8 s and respectively
