Nanometer is a distance of one billionth of a meter, which is an extremely small distance. (1x10-9m)

The nanometer, or nm, is a common unit used to describe wavelengths of light or other electromagnetic radiation such as UV. For example, green light has wavelengths of about 500-550 nm, while violet light has wavelengths of about 400-450 nm.

The nanometer is also used extensively in the new fields of semiconductors and nanotechnology.
