Hi All! PLEASE correct something if I say it like it's an axiom but it's not quite right, I'd like conformation of my research: So as far as I can tell there is some contention about what an actual photon 'is'. So when an electron goes from high state to low state it releases a 'photon' in a packet of quanta 'particles'. These travel according to the inverse square law AS A WAVE, together. Thus since this wave is made of particles moving straight outward, the wave DOES NOT HAVE AN AMPLITUDE but the AMOUNT OF PHOTONS present in a space (with superposition) affects the intensity. So the mechanical 'energy is proportional to the square of the amplitude' does not apply, only E = hf. I have drawn a picture of a single particle photon as a black sphere, I'm not sure if this sphere particle actually exists or just the field lines that come out of it at different strengths as it moves. If someone could offer their thoughts that would be nice. If this is all correct I have a question. THANKS!!
