Incandescence is the emission of electromagnetic radiation (including visible light) from a hot body as a result of its high temperature.[1] The term derives from the Latin verb incandescere, to glow white.[2] Although an object does not have to glow brightly or glow white in order to be considered incandescent. A common use of incandescence is the incandescent light bulb, now being phased out.[as of?]
Incandescence is due to thermal radiation. In some fields, incandescence refers specifically to visible light, while thermal radiation also covers infrared or any other electromagnetic radiation. In other fields, all thermal radiation is considered incandescence.
The state in which a heated body, naturally incapable of emitting light, becomes luminous, is called a state of incandescence.
