9 Questions
What is the name of the law that explains the observed spectral distribution of a black body radiation?
Stefan-Boltzmann’s Law
Who first showed the energy density of radiation of wavelength λ and λ + dλ from a cavity (i.e. black body) of temperature T?
Wien
What is the main limitation of Wien's radiation formula?
It explains only the experimental results fairly well for low wavelength region
