The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its periodâthe time interval between beatsâis half a second (that is, 60 seconds divided by 120 beats).
The frequency is the number of cycles per second. For example, if the period of a pendulum is 2 seconds, it s frequency is 0.5 cycles per second (0.5 Hz). When to use periodor frequency While both period and frequency tell us the same information, we usually use period when cycles are slower than a few per second.
