The "Frequency" of one Photon? If one could measure a photon passing by a given point, what is the time it takes for the leading edge of the theoretical particle of the photon itself to pass by that given point from the leading edge to trailing edge of just the particle size itself (not any fields or wave aspects, just the particle) The reason why i ask is that one cannot express the "frequency" of just one photon, (you need many to comprise a frequency) and you cannot use (hertz) because that implies the event lasts one complete second which of course the absorption process of one photon would not take. So in effect the answer to my question would be the actual "frequency" of one photon. It will be one cycle per ___________??? Thanks in Advance!
