Incandescence is the emission of light (visible electromagnetic radiation) from a hot body due to its temperature. The term derives from the verb incandesce, to grow white. The incandescence of a theoretically perfectly black object is known as black body radiation, which is described by relatively simple mathematical equations. For a black body, the distribution of energy emissions across the electromagnetic spectrum is described by Planck's law. The total power emitted by radiation from a bl… (More on Incandescence)
