Black-body radiation - Wikipedia
Learn about the thermal electromagnetic radiation emitted by a black body, an idealized opaque, non-reflective body in thermodynamic equilibrium. Find out the theory, spectrum, applications, history and references of black-body radiation.
6.2: Blackbody Radiation - Physics LibreTexts
Learn about blackbody radiation, the intensity distribution of electromagnetic waves emitted by a perfect absorber at a given temperature. Find out how Wien's and Stefan's laws describe the wavelength and intensity of blackbody radiation.
6.1 Blackbody Radiation - University Physics Volume 3 - OpenStax
The blackbody radiation curve was known experimentally, but its shape eluded physical explanation until the year 1900. The physical model of a blackbody at temperature T is that of the electromagnetic waves enclosed in a cavity (see Figure 6.2) and at thermodynamic equilibrium with the cavity walls. The waves can exchange energy with the walls.
