WebKirchhoff's law of heat radiation states that the emissivity of radiating bodies is equal to their absorptivity. Kirchhoff's law seems to remain valid in the case of nonequilibrium if induced emission is considered as negative absorption as was first shown for freely radiating weakly absorbing bodies.

Polarized Emissivity and Kirchhoff

Web17 mei 2015 · This is Kirchhoff's law: The ratio of the emissive to absorptive power for radiation of a given wavelength is the same for all bodies at the same temperature. A way of clarifying this is to compare two different bodies, placed separately in the interior. The body discussed above, has equilibrium state: a λ d Q = e λ d λ. WebKirchhoff's Laws work for every circuit, no matter the number of batteries or resistor configuration. KCL tells you about the sum of currents at each specific node in the circuit. … spectre feats
