WebKirchhoff's Law and Emissivity. Gustav Robert Kirchhoff (1824–1887) stated in 1860 that “at thermal equilibrium, the power radiated by an object must be equal to the power absorbed .”. This leads to the observation that if an object absorbs 100 percent of the radiation incident upon it, it must reradiate 100 percent.

WebFrom the second law of thermodynamics Kirchhoff showed that blackbody radiation’s energy densities must be universal functions. Based on prior theoretical (Stefan–Boltzmann and the Wien’s displacement law) and new experimental developments, Planck proposed a distribution law that could fit both high and low frequency measurements. WebIn the atmospheric sciences, "electromagnetic radiation" is commonly referred to as simply "radiation." Radiation is the basis for remote sensing technology. Because radiation can transport energy without a medium, it is the only way in which the earth interacts with the rest of the universe. Radiation theory starts with the fundamental law ...
