Energy in EM wave

    Hmmm.... If U ∝ E2, E ∝ a and a ∝ ω, how can Uavg not be dependent on ω ?

    I believe that the key word here is AVERAGE.

    Why ? If Emax depends on ω, then so should Uavg.

    Have I missunderstood something ? Will the amplitude of E increase when the oscillating charge accelerates faster ?
