Wien's displacement law

  1. Aug 14, 2012 #1
    Wein's displacement law is

    E (T,ν) = = v3F (v/T)

    This is from Omnes' book on QM

    He doesn't explain why the total radiation is infinite. I'd like to know why.

    E is increasing with [itex]\nu[/itex], if you integrate [itex]\nu[/itex] from 0 to infinity to get the full energy content (as all frequencies are allowed) you will see that the integral diverges.
