The three characteristics that make a glowing piece of charcoal a blackbody radiator are:
- It absorbs most of the EMR it receives: A blackbody radiator absorbs all incident electromagnetic radiation (EMR) falling on it. In the case of glowing charcoal, it absorbs radiation from its surroundings, including visible light.
- It emits a variety of EMR wavelengths: A continuous spectrum of EMR is emitted by a blackbody radiator at all wavelengths.. The spectrum of radiation emitted by the glowing charcoal spans from infrared to visible light. The color of the charcoal's glow depends on the temperature of the charcoal and the peak of the emitted radiation's wavelength.
- The frequencies of EMR it emits depend on its temperature: A blackbody radiator's emitted radiation increases with its temperature. As the temperature of the charcoal increases, the emitted radiation also increases, causing the color of the charcoal to change. The frequency distribution of the emitted radiation is determined solely by the temperature of the charcoal and is independent of the material of the radiator.
In summary, a glowing piece of charcoal is an example of a blackbody radiator because it absorbs all incident EMR, emits a continuous spectrum of EMR at all wavelengths, and its emitted radiation is determined solely by its temperature.
