Infrarubie

Image de du gentes in medial infrarubie ("termal") lúmine (color fals)

Infrarubie (IR) es radiation electromagnetic de un unde-longore plu long quam to de lúmine visibil; li spectre infrarubi comensa al borde nominal de rubie visibil a 0,7 micrometres (μm) e extende conventionalmen a 300 μm.

Ti longores undic coresponde a un extension frequential de approximatemente 430 a 1 THz,[1] e include li max parte del radiation termal emisset per coses proxim temperatura ambient. Microscopicamen, lúmine IR es tipicamen emisset o absorbet per molecules quando les changea lor rotational e vibrational movementes.

Luce del Sole al zenite provide un iradiantie de circa 1 kilowatt per metre quadrat a nivelle del mar. De ti energie, 527 watts es radiation infrarubi, 445 watts es lúmine visibil, e 32 watts es radiation ultravioletti.[2]
