Frequency \(f\) is defined to be the number of events per unit time. For periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is \[f = \dfrac{1}{T},\] The SI unit for frequency is the cycle per second, which is defined to be a hertz (Hz):
The angular frequency \(\omega\) is measured in units of radians per second ( \(\mathrm{rad} / \mathrm{s}\) ); the frequency \(f\) is measured in units of hertz \((\mathrm{Hz})\), where \(1 \mathrm{~Hz}=1 / \mathrm{sec}\). The reciprocal of the frequency is the period \(T\), and is the time required to complete one cycle of the motion:
In mathematical terms, the frequency is the number of complete vibrational cycles of a medium per a given amount of time. Given this definition, it is reasonable that the quantity frequency would have units of cycles/second, waves/second, vibrations/second, or something/second.
