A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.

WebMar 26, 2024 · $\begingroup$ It is more clear, thanks. Allright so to summarize: a black body is a body that absorbs everything and reflects nothing. We can model it by a tiny hole with a huge cavity behind. The tiny hole combined to the cavity is here to model the fact a light beam entering will necessary go out once it is thermalized (because very little … WebIf a body emits the maximum amount of radiation at a particular temperature and wavelength, or equivalently absorbs all of the incident radiation, it is called a black body. For a black body, Aλ = 1 and Rλ = Tλ = 0 for all wavelengths. Black-body radiation is characterized by the following properties: 1.
WebAnswer (1 of 3): A black body is a body which absorbs all the radiation incident on itself, and radiates back all these radiations. That's why umbrellas are coulored black. Black body radiation was the source of experiment for Planck which helped in discovering the Planck's Quantum Theory.
