Emission of electromagnetic radiation from a hot body
See also Incandescent (album), Incandescence (novel), or thermal radiation.
Hot metal work glows with visible light. This thermal radiation also extends into the infrared, invisible to the human eye and the camera the image was taken with, but an infrared camera could show it (See Thermography).The incandescent metal embers of the spark used to light this Bunsen burner emit light ranging in color from white to orange to yellow to red or to blue. This change correlates with their temperature as they cool in the air. The flame itself is not incandescent, as its blue color comes from the quantized transitions that result from the oxidation of CH radicals.
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] A common use of incandescence is the incandescent light bulb, now being phased out.[as of?]
Incandescence is due to thermal radiation. It usually refers specifically to visible light, while thermal radiation refers also to infrared or any other electromagnetic radiation.
