Infrared - Wikipedia, the free encyclopedia
Infrared ( IR ) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400–700 nm), but shorter than that of terahertz radiation (100 µm – 1 mm) and microwave...

Infrared Imaging tutorial from Electrophysics describes the discovery of Infrared Radiation. ... Herschel’s experiment was important not only because it lead to the discovery of infrared light, but because it was the first experiment that showed there were forms of light not visible to the human eye.

Infrared Astronomy From Earth Orbit ... In the 1970s, astronomers around the world began to consider the possibility of placing an infrared telescope on a satellite in orbit around the Earth. This telescope would be above the Earth's atmosphere and could view the sky at the far-infrared wavelengths which were difficult...

Infrared Theory ... History of Infrared ... Infrared radiation was discovered in 1800 by Sir William Herschel while he was measuring the temperature of the various colors of the visible spectrum separated by a prism. Herschel observed that the temperature of his thermometer increased as he moved it from the blue to the red.
