The unit is named for Heinrich Rudolph Hertz, the first person to prove the existence of electromagnetic waves. Hertz can be used to measure any periodic event; the most common uses for hertz are to describe radio and audio frequencies, more or less sinusoidal contexts in which case a frequency of 1 Hz is equal to one cycle per second.
