- Blackbody radiation is a term used to describe the relationship between an object's temperature and the wavelength of electromagnetic radiation it emits12. A black body is an idealized object that absorbs all electromagnetic radiation it comes in contact with and emits thermal radiation in a continuous spectrum according to its temperature1. The radiation emitted by a black body is determined by the temperature alone, not by the body's shape or composition2. At room temperature, a black body radiates mostly in the infrared spectrum, which cannot be perceived by the human eye, but can be sensed by some reptiles3.

A black body is an idealized object that absorbs all electromagnetic radiation it comes in contact with. It then emits thermal radiation in a continuous spectrum according to its temperature.lco.global/spacebook/light/black-body-radiation/A black body in thermal equilibrium (that is, at a constant temperature) emits electromagnetic black-body radiation. The radiation is emitted according to Planck's law, meaning that it has a spectrum that is determined by the temperature alone (see figure at right), not by the body's shape or composition.en.wikipedia.org/wiki/Black_bodyA black body at room temperature (23 °C (296 K; 73 °F)) radiates mostly in the infrared spectrum, which cannot be perceived by the human eye, but can be sensed by some reptiles.en.wikipedia.org/wiki/Black-body_radiation Black body - Wikipedia
