Witryna7 maj 2024 · If a blackbody reflected the light that was incident upon it at some wavelength range or allowed that light to pass through it, then the intrinsic spectrum of light emerging from the body, if it were in thermal equilibrium, would be missing the specific wavelengths that could not be absorbed. The definition of a blackbody is that … WitrynaIn late 1859, Kirchhoff had defined a black body as an object that is a perfect emitter and absorber of radiation. By the 1890s, various experimental and theoretical attempts …
