Question

what is wave length

Answer 1

{The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.}A wavelength is a measure of distance between two identical peaks (high points) or troughs (low points) in a wave -- a repeating pattern of traveling energy like light or sound.

Wavelength is inversely related to frequency, which refers to the number of wave cycles per second. The higher the frequency of a signal, the shorter the wavelength. A wavelength can be calculated by dividing the velocity of a wave by its frequency.

Answer 2

The wavelength is a homogeneous physical quantity at a length, characteristic of a monochromatic wave in a homogeneous medium, defined as the distance between two consecutive maximal of the amplitude.


The wavelength depends on the speed or speed of propagation of the wave in the medium it passes through. When the wave passes from one medium to another, in which its velocity is different, its frequency remains unchanged, but its wavelength varies.

When the wave is not monochromatic, the harmonic analysis makes it possible to decompose it into a sum of monochromatic waves. Physical phenomena are never strictly periodic; The spectral analysis leads to an infinite sum of monochromatic waves. We then consider the dominant wavelength, that is to say that which corresponds to the frequency that carries the most energy, or to the central frequency of the range that carries the most energy.

Wavelengths are commonly used in acoustics, radio, and optics.
