Just two days ago I attended a lecture held by a professor at UiO who discussed the need to resolve the wave/particle duality model of light. He was unsatisfied by the deterministic approach to the problem (Bohr's principle). In general, he viewed the photon model as poorly defined and poorly founded, claiming the the historical experiments thought to have verified the photon theory could be explained with the wave model, with the exception of the light splitter experiment. If we would model the photon differently, not as a particle, but as a pulse of EM radiation lasting a time [tex]\tau[/tex] consisting of radiation with a period [tex]T[/tex] and an E-field [tex]E(t)[/tex], would it be possible to express the energy carried by the pulse using these three properties and fundamental constants in a way that satifsies previous measurements? I have thought about the idea, and I think the energy would have to be proportional to [tex]\tau[/tex] and the integral of [tex]E^2(t)[/tex] over the pulse and inversely proportional to [tex]T[/tex] (known from previous measurements). I also consider [tex]c[/tex], [tex]\epsilon_0[/tex] and [tex]h[/tex] as neccesary constants, but I have been unable to reach units of joules using combinations of these. Does anyone have any thought on the matter?
