Frequency is the number of occurrences or cycles of a repeating event per unit of time. It is often measured in Hertz (Hz), which is the number of cycles per second. In other words, frequency is a measure of how often something happens.

Frequency and wavelength are inversely proportional to each other. As the frequency of a wave increases, its wavelength decreases, and vice versa. This relationship is described by the formula: c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency.

Frequency is all around us. For example, the frequency of a guitar string is the number of vibrations per second, the frequency of a sound wave is the number of oscillations per second, and the frequency of a light wave is the number of oscillations per second.

Frequency is used in many technologies, including radio communication, radar, and medical imaging. For example, radio frequencies are used to transmit signals over long distances, while medical imaging technologies use specific frequencies of electromagnetic radiation to create images of the body.
