Periodic waves at shallow water, wavelength is denoted Î». A wavelength is the length of the shortest repeating part of a sine wave. All waves can be formed by adding up sine waves. That is, every wave is a total of sine waves, which may be identified by Fourier analysis. Waves are everywhere.
White light is separated into the different colors (=wavelengths) of light by passing it through a prism. Wavelength is defined as the distance from peak to peak (or trough to trough). The energy of is inversely porportional to the wavelength: longer wavelengths have less energy than do shorter ones.
