Ultraviolet
Electromagnetic radiation of a wavelength between the shortest visible violet and low energy x-rays.
Electromagnetic radiation of a wavelength between the shortest visible violet and low energy x-rays.

ULTRAVIOLET
Electromagnetic radiation that has a wavelength shorter than visible light and longer than x-rays. Although it accounts for only 4 to 5 percent of the total energy of insolation, it is responsible for many complex photochemical reactions, such as fluorescence and the formation of ozone.

ultraviolet (UV)
Electromagnetic radiation with wavelengths between that of visible violet light and X-rays; it ranges from 400 to 4 nanometers. Ultraviolet is subdivided into near (NUV) 400 to 300 nanometers, far (FUV) 300 to 200 nanometers, extreme (XUV) 200 to 100 nanometers, and vacuum (VUV) 100 to 4 nanometers. Most of the potentially hazardous UV radiation emitted by the Sun is absorbed by the ozone layer. [See also radiation.] updraft A rising air current.

Ultraviolet
A type of electromagnetic radiation with a wavelength, shorter than that of visible light. It is defined to be within the range of 10 to 400 nanometres. Electromagnetic radiation with a wavelength shorter than 10 nanometres is known as X-rays or gamma rays.

ultraviolet (uv)
The portion of the electromagnetic spectrum in which the longest wavelength is just below the visible spectrum, extending from approximately 4 nm to approximately 400 nm. Note: Some authorities place the lower limit of uv at values between 1 and 40 nm, 1 nm being the upper wavelength limit of x-rays. The 400-nm limit is the lowest visible wavelength, i.e., the highest visible frequency, violet.

ULTRAVIOLET
Lamp that gives off two different wave lengths-Shortwave and Longwave. Shortwave UV light will highlight phosphor tagging, either in the printing ink or the coating on a stamp. Longwave UV light will spot fluorescence in the paper of a stamp or cover.

Ultraviolet
Light that is so blue humans cannot see it. A band of the electromagnetic spectrum between the visible and the X-ray. Photons of ultraviolet light are more energetic than photons of visible light.

Ultraviolet Definition from Encyclopedia Dictionaries & Glossaries
| Wikipedia English - The Free Encyclopedia |
Ultraviolet
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum starts with wavelengths slightly shorter than the wavelengths humans identify as the color violet (purple).
