What is the period of a 60 Hz wave?

The period of a wave is the reciprocal of its frequency. To determine the period for a 60 Hz wave, you use the formula:

[ \text{Period (T)} = \frac{1}{\text{Frequency (f)}} ]

Substituting the frequency of 60 Hz into the formula:

[ T = \frac{1}{60 , \text{Hz}} ]

Calculating this gives:

[ T = \frac{1}{60} \approx 0.01667 , \text{seconds} ]

This result rounds to approximately 0.017 seconds, which corresponds closely to option A, 0.016 sec. Being familiar with how frequency and period relate to each other is essential in understanding oscillatory and wave phenomena in power engineering.
