Planck Function

(Planck's Law)
(yields black body curve)

The Planck Function is a function of Wavelength and Temperature that describes the spectral Radiance at each wavelength in Black-Body Radiation.

Radiance is the quantity of radiation emitted through a surface into a given solid angle, spectral radiance being the radiance at a given wavelength.
