Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity and to distinguish it from spatial frequency.
Frequency is defined as the number of waves that pass a fixed point in unit time. Learn the concepts of frequency, time period and angular frequency along with definition and formulas at BYJU'S.
- A wave is a disturbance that travels through a medium from one location to another location.
- We define the frequency of a sinusoidal wave as the number of complete oscillations made by any element of the wave per unit of time.
- The time period of oscillation of a wave is defined as the time taken by any string element to complete an oscillation.
- The angular frequency refers to the angular displacement of any wave element per unit of time or the rate of change of the waveform phase.
