Period (physics)

A time period (denoted by 'T'' ) is the time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds'. "Frequency" and time "period" are in a reciprocal relationship that can be expressed mathematically as: T = 1/f or as: f = 1/T.
