WebA black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The name "black body" is given because it absorbs all colors of light. A black body also emits black-body radiation.

Figure 1.2.1: Relationship between the temperature of an object and the spectrum of blackbody radiation it emits. At relatively low temperatures, most radiation is emitted at wavelengths longer than 700 nm, which is in the infrared portion of the spectrum.
WebA blackbody is an object that absorbs all of the radiation that it receives (that is, it does not reflect any light, nor does it allow any light to pass through it and out the other side).

Web6 Kirchhoff’s law. The Kirchhoff’s law states that the emissivity, ελ, of a medium is equal to the absorptivity, Αλ, of this medium under thermodynamic equilibrium: εελ = Αλ [4.8] where ελ is defined as the ratio of the emitting intensity to the Planck function; Αλ is defined as the ratio of the absorbed intensity to the Planck function.
WebMar 3, 2024 · blackbody, also spelled black body, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black.
