Which term for the number of periods or regularly occurring events per unit time?

Explanation:
Frequency is the number of periods or regularly occurring events per unit time. It tells you how often something repeats in a given timeframe, such as cycles per second. The frequency is the reciprocal of the period—the time it takes for one cycle—so f = 1/T. In practice, frequency is measured in hertz, meaning cycles per second. This distinguishes it from period, which is the time per cycle, and from wavelength (distance per cycle) and amplitude (how tall the oscillation is).
