lac-bo+y Ra+iation• lac-bo+y !a+iation is radiation

produced by heated objects, particularlyfrom a ind of special object that is made so

it will absorb all radiation !visible light,infrared light, ultraviolet light, etc." that fallson it, and so that it will also radiate at allfre#uencies that heat energy produces in it.

•

$he term blac- bo+y is often used to referto objects that glow brightly.
