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 number of cycles in a second is one Hertz (Hz), after the German physicist. Therefore 1Hz equals one cycle per second. Period: the time it takes to complete one cycle. (see Figure 03) Figure 03. Wavelength: The distance sound travels during one period, regardless of frequency.
