| ultraviolet radiation |
Electromagnetic radiation at wavelengths between 10 and 400 nanometers lying just beyond the high-energy (violet) end of the visible-light band of the solar spectrum; about 5% of the radiation the Earth receives from the sun, much of which is absorbed by the atmosphere. UV-A = 315 to 400 nanometers wavelength; UV-B = 280 to 315 nanometers; UV-C = 100 to 280 nanometers. UV-B is the part of the spectrum that causes sunburn and has been linked to skin cancer.

(UV) The invisible part of the light spectrum whose rays have wavelengths shorter than the violet end of the visible spectrum and longer than X rays. UVA and UVB light are harmful to your eyes and skin.

| ultraviolet radiation |
electromagnetic radiation in the wavelength range from 100 to 400 nanometers. It is shorter and more energetic than visible light but has essentially the same composition. Depending on its wavelength, it penetrates skin to different levels (more deeply in the case of UVA than UVB) and triggers different biological effects.

| ultraviolet radiation |
The energy range just beyond the violet end of the visible spectrum. Although ultraviolet radiation constitutes only about 5 percent of the total energy emitted from the sun, it is the major energy source for the stratosphere and mesosphere, playing a dominant role in both energy balance and chemical composition.
