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.
Asker's rating. 1  In this instance, the abbreviation 'nm' stands for Nanometer (.000000001 (10^-9) of a meter) - a unit of measurement and in the case of Ultra Violet Light or UVA, it is used to indicate wavelength. 2  nm stands for Nanometer. 3  nanometers. 4  Uv Light Stand. 5  nm stands for nano-metre. Nano meter is defined as 10^-9 meters or you can conceive that if you break apart a metre into 1000000000 equal parts, one of these is a nanometre or nm. As wavelength and amplitude of light waves are very very small, they are represented in nano metres instead of meters.
