WebFeb 3, 2024 · Theoretical Proof of Kirchhoff’s Law of Radiation: Let us consider two bodies A and B suspended in a constant temperature enclosure. B is a perfectly black body. After some time both A and B will attain the same temperature as that of the enclosure. By Prevost heat exchange theory in this state also every body will emit and … WebA blackbody is an idealized physical body that has specific properties. By definition, a black body in thermal equilibrium emissivity of ε = 1.0. Real objects do not radiate as …
