PlanckRadiationLaw

PlanckRadiationLaw[temperature, λ] returns the spectral radiance for the specified temperature and wavelength λ.

• PlanckRadiationLaw[temperature, f] returns the spectral radiance for the specified temperature and frequency f.
• PlanckRadiationLaw[temperature, property] returns the value of the property for the specified temperature.
• PlanckRadiationLaw[temperature, {λ1, λ2}] returns the integrated result over the wavelength range λ1 to λ2.
• PlanckRadiationLaw[temperature, {f1, f2}] returns the integrated result over the frequency range f1 to f2.
