A Point source of light has radial symmetry.
If the source gets attenuated so that only a single photon is leaving each hour, can I still argue, that the field of the single photon is radial but the photon is detected on an arbitrary (random) point on the sphere, like it is the case for the wave function of a material particle?
In this case there could be interference caused by spatially very distant interfering objects (e.g. gravitation of stars, ...)
Or does the emitted photon have a narrow radiation coil from beginning?
