Timeline for Why can't we duplicate the double slit experiment with two parrallel sources of light.. why must the light enter the two slits externally?

Therefore is an explanation incapable of addressing the points you mention. On the other hand QM explanations of the phenomenon (the ones I've seen) does not attempt to describe in terms of quanta, but in terms of a plane wave function with single momentum, so I think when there your questions remain unanswered. I think they are valid though. | |
| Oct 15, 2016 at 6:21 | comment | added | HolgerFiedler | mhleo, are two coherent sources really needed? Even behind a sharp edge a intensity distribution of light appears. Next, monochrome light is a good choice to get clear fringes Coherent light source means the phases of the light quanta are equal. This isn't needed for interference. The theory stated that the slits make the light in phase. Unanswered is the question how the slits make the incomming light quanta coherent. | |
