Infrared Radiation
(gcide) | Infrared Radiation \In`fra*red" Ra`di*a"tion\, n. [Infra- +
red.] (Physics)
electromagnetic radiation having a wavelength of between 700
nanometers and 1 millimeter.
Note: Infrared radiation is that electromagnetic radiation
lying between the visible spectrum and the longest
microwaves. It may be absorbed by matter in a manner
specific to the absorbing substance, causing increased
vibration of molecules. The infrared absorption
spectrum of a chemical compound is often very specific,
and the infrared absorption spectrum is therefore used
to help identify chemical substances. Infrared
radiation is used in certain communication devices,
such as television remote controls and communication
devices between computers or between computers and
peripherals.
