PlanckRadiationLaw[temperature,property]
returns the value of the property for the specified temperature.

PlanckRadiationLaw[temperature,{λ1,λ2}]
returns the integrated result of the spectral radiance over the wavelength range λ1 to λ2.

PlanckRadiationLaw[temperature,{f1,f2}]
returns the integrated result of the spectral radiance over the frequency range f1 to f2.

DetailsDetails

  • Inputs temperature, λ, and f should be Quantity objects.
  • Full properties of PlanckRadiationLaw can be obtained by using PlanckRadiationLaw["Properties"].
  • Properties include:
  • "MaxFrequency"frequency at peak spectral radiance
    "MaxFrequencyColor"color of the peak frequency
    "MaxWavelength"wavelength at peak spectral radiance
