The frequency of waves is given in Hertz (Hz). The quantity of cycles or oscillations that take place over a specific time period is known as frequency, which is a key characteristic of waves.
Hertz, which expresses the number of cycles per second, is used to express frequency. Cycles per second are measured in Hertz. The wavelength of the wave is proportional to the frequency, which is measured in cycles per unit of time.
Higher frequencies in the context of sound waves are seen as having higher-pitched noises, whilst lower frequencies are perceived as having lower-pitched sounds.
