I know people get tired of answering questions about photons, but I have a question regarding the best way to think of how light (i.e. E-M waves) are created. Several books and educational resources say that a light wave is created by "vibrating electrical charges." But my understanding of photons is that we don't have much of a model for how they are generated. If you don't like conflating/blending discussion of "photon"s versus "light waves," then I would put my concern this way: When an electron changes energy level and emits a photon, one cannot really say it "vibrates" in the way that we think of, say, a drumhead vibrating. How wrong is it to say that one can speak of short time envelope [a "delta t" in terms of the Heisenberg relationship] "between" the time when the electron was in one energy state and when it was in another, and during this time the light-wave/photon gestated?
