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.
(This is because the product of frequency and wavelength is always the speed of the wave. For light, that speed is constant.) Mathematically: frequency = speed of light/wavelength. An electromagnetic wave is a synonym for light, because it consists of waves of electric and magnetic fields. Wavelength is the distance from one peak of an electromagnetic wave to the next.
