Entropy of blackbody radiation

    Can someone point out any information (derivation or where it comes from) about this equation:

    [tex]S = v\int_0^\infty\phi(\rho,\nu)d\nu[/tex]

    [tex]\nu[/tex] is frequency of radiation. [tex]\rho(\nu)[/tex] is radiation energy, v is volume.

    I'm getting this from Einstein's photoelectric effect paper.

    Thanks a lot!

    Well,i haven't seen it in this actual form.Surely it wasn't an invention by Einstein.Did you check the formula for the entropy of BB radiation in a standard SM textbook,like Schwabl or Greiner...?Can u see the connection,then ?

    No. I haven't studied statistical mechanics (beyond very basic ideas of entropy), and don't have a text to compare.

    I figured I'd probably need to have a good understanding of statistical mechanics before I could get through this paper. :yuck:

    edit: Which SM text would you recommend?

    Greiner's book in his series seemed accessible / readable enough and provided a wealth of worked out examples.
