Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in hertz which is equal to one event per second.

Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.Wavelength is inversely proportional to frequency. This means the longer the wavelength, lower the frequency.
