Emission and absorption of radiation - Black body radiation
WebHere is the intensity-wavelength graph for the Sun. As the surface temperature of a hot body such as a star increases: the intensity of radiation it emits increases WebWien's displacement law states that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature. The shift of that peak is a direct consequence of the Planck radiation law, which describes the spectral brightness or intensity of black-body radiation as a … philippinen hotel am strand
