Fig. 9-5. Planck's Blackbody Radiation Curves as a Function of Wavelength and Frequency [Chen, 1985]. Planck's law defines the shape of the curve over all frequencies, the Stefan-Boltzmann's law defines the area under the curve (the total energy emitted over all wavelengths), and Wien's displacement law defines the wavelength of maximum radiance.
