Thank you for the opportunity to help you with your question!

Derivation from Planck's Law

Planck's law for the spectrum of black body radiation predicts the Wien displacement law and may be used to numerically evaluate the constant relating temperature and peak wavelength (or frequency). According to one form of that law, the black body spectral radiance (power per emitting area per solid angle per unit wavelength) is given by:
