WebMar 24, 2014 · Planck’s law describes the electromagnetic radiation emitted by a black body in thermal equilibrium at a definite temperature. The law is named after Max Planck, who originally proposed it in 1900. It is a pioneer result of modern physics and quantum theory. Intensity of light emitted from a black body at any given frequency. WebThermal radiation from natural surfaces, such as the land surface, ... As described in Chapter 2, by Kirchhoff's law the spectral emissivity of a material is equal to its spectral absorptance under thermal equilibrium conditions. Therefore, the emissivity can also be derived from two other optical properties, that is, ...
