Ultraviolet Light

Electromagnetic radiation with wavelength longer than that of x-rays but shorter than that of visible light, wavelengths range from 1x10^-9m to 400x10^-9m. Ultraviolet light can break some chemical bonds and cause cell damage.

Used for exposing photoresist in making semiconductor devices.
