Infrared vs. Ultraviolet

Infrarednoun

electromagnetic radiation of a wavelength longer than visible light, but shorter than microwave radiation, having a wavelength between 700 nm and 1 mm

Infraredadjective

Having the wavelength in the infrared.

Infraredadjective

In the infrared spectrum.

Infraredadjective

Lying outside the visible spectrum at its red end; - said of rays having a longer wavelength (and thus less refrangible) than the extreme red rays, specifically those electromagnetic waves having a wavelength of between 700 nanometers and 1 millimeter.

Infraredadjective

relating to, using, or producing infrared radiation.

Infraredadjective

affected by infrared radiation; as, infrared detector; infrared film.

Infrarednoun

the infrared part of the electromagnetic spectrum; electromagnetic wave frequencies below the visible range;

Infrarednoun

electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves

Infraredadjective

having or employing wavelengths longer than light but shorter than radio waves; lying outside the visible spectrum at its red end;

Infrared

Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye.

Ultravioletadjective

of electromagnetic radiation beyond (higher in frequency than) light visible to the human eye; radiation with wavelengths from 380 nanometre - 10 nanometre

Ultravioletnoun

Ultraviolet colour.

Ultravioletadjective

Lying outside the visible spectrum at its blue-violet end; - said of light more refrangible (i. e. having a shorter wavelength) than the extreme violet rays of the visible spectrum. Electromagnetic radiation with wavelengths shorter than those of ultrviolet light are not usually considered as light waves, but are classified differently. The ultraviolet region of the electromagnetic spectrum is generally considered as comprising those electromagnetic emissions with wavelengths lying between those of visible light and those of X-rays, i. e. between 4000 Angstroms and 100 Angstroms.

Ultravioletnoun

radiation lying in the ultraviolet range; wave lengths shorter than light but longer than X rays

Ultravioletadjective

having or employing wavelengths shorter than light but longer than X-rays; lying outside the visible spectrum at its violet end;

Ultraviolet

Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
