Timeline for In double-slit experiment, if one directs coherent light from two sources into each slit separetely, is ridges pattern expected to be seen?

At shorter wavelengths, photons are detectable, but it is a mistake to think of waves as composed of photons in flight: it will lead you to confusion and incorrect reasoning. My friends who design x-ray diffraction gratings use classical electrodynamics. "Looks like antenna theory to me." But photons show up at my detectors. The intensity of the waves predicts where the photons will appear. | |

| Nov 10, 2022 at 2:44 | comment | added | Martian2020 | AM is interesting idea, as for the doubt-slit, e.g. personal.math.ubc.ca/~cass/courses/m309-03a/m309-projects/fun/… shows where ridge is, but if not same photon, then 1st slit is out-of-phase (even same length results in arbitrary phase difference) with the other, is it not? And so ridge position will shift each time. | |
