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 … WitrynaWhile Planck's radiation law was readily accepted, the importance of its conceptual novelty - its basis in energy quantization - took several more years to gain notice.
