The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.

The time interval T required to complete one oscillation is called the period. A related quantity is the frequency f, which is the number of vibrations the system makes per unit of time. The frequency is the reciprocal of the period and is measured in units of Hertz, abbreviated Hz; 1 Hz = 1 sâ1.
