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, 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 800-900 nm, while violet light has wavelengths of about 20-50 nm.
The nanometer is also used extensively in the new fields of [[semiconductor|semiconductors]] and [[nanotechnology]].
