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.
Wavelength is a measure of the distance between two crests or two troughs of a wave. The greater the wavelength, the more energy a wave has. AM radio stations have a big wavelength. You might have tuned the radio dial at night and heard stations that were far away and unable to be heard during the daytime.
