Infrared - Reflexions

Infrared

Electromagnetic radiation (or “light”) that is propagated in wavelengths that are invisible to the naked eye, ranging from 0.7 to 100 micrometers. Infrared radiation is associated with heat, because many objects emit infrared radiation spontaneously at room temperature. Infrared light is used in many technologies. -night-vision equipment (warmer objects show up as brighter) ; -infrared thermography that allows one to measure temperatures at a distance ; -missile guidance systems (infrared detectors guide missiles toward a source of heat, for example the jet engine of a targeted aircraft) ; -communication over short distances from a computer to its peripheral devices.
