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).
Angular period, T, is defined as the time required to complete one revolution and is related to frequency by the equation: Since we know that the frequency of the second hand is 1 / 60 Hz, we can quickly see that the period of the second hand is 60 s. It takes 60 seconds for the second hand to complete a revolution, so the period of the second hand is 60 seconds. Period and angular velocity are related by the equation
