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).
This period is the reciprocal of the frequency. This is written as: T = 1/f. where T is the period and f is the frequency. The SI unit for frequency is the hertz (Hz), which is equal to 1/s, or once per second. Frequency is encountered many times in physics. A few highly important instances are listed here. All waves in physics are said to have frequency.
