I Can the Planck equation be derived by considering phonons?

  1. Jul 19, 2016 #1
    As far as I understand, phonons are just thermal vibrations of atoms in a lattice and blackbody radiation is just the radiation emittied due to thermal oscillations accelerating the atoms back and forth. Is there any example of a derivation of the planck equation from considering black body radiation as a combination of these two principles?

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    The phonons in a solid at thermal equilibrium follow the Plank distribution as well.
    I don't see what are the "two principles" you mention in the OP.
    The Plank distribution ca be derived from quantum statistical considerations, applied to bosons.
