that also can be treated (modelled) as if they are waves or rays depending
upon the phenomenon under consideration. What I remember is that for a
visible light laser (that is obviously fairly coherent), the envelope
defining the photon is on the order of a meter. Thus there are more than a
million wavelengths of light in such a photon. Can someone else verify
this; it has been a few years since I have looked at this.
