# Wavelength

Wavelength. The distance existing between crests or valleys consecutive is what we call length wave. The wavelength of a wave describes how long the wave is . Waves water in the ocean , waves air , and waves of electromagnetic radiation having wavelengths. The wavelength represents the actual distance traveled by a wave that does not always coincide with the distance from the medium or the particles in which the wave propagates.

## Wavelength equation.

The Greek letter “λ” (lambda) is used to represent the wavelength in equations. The wavelength is inversely proportional to the frequency of the wave. A long wavelength corresponds to a low frequency, while a short wavelength corresponds to a high frequency. The unit of measurement of the wavelength is the meter , like that of any other length. Wavelength can be from very small, measured using from one nanometer (one billionth of a meter) and angstroms (ten billionth of a meter) to hundreds of meters.

## Representation.

λ = c / f. where “λ” is the wavelength, “c” is the speed of propagation of the wave, and “f” is frequency. Wavelength and frequency are inversely proportional, that is, at high frequencies, small wavelengths and vice versa.
