Planck's law revisited

I review a textbook derivation of Planck's formula for spatial density of radiation energy. I point out at one inconsistency, and a couple of factitious assumptions used in derivation. I propose a derivation more aligned with quantum mechanical principles. I show the de-coherence of oscillator modes is the major factor in Planck's law
