Reading about diffraction of EM radiation on edges, slits and multi slits as well as about electron diffraction behind a wire I came to the conclusion that the intensity distributions on an observers screen is the result of the interaction between radiation (electron beam) and a quantized field of surface electrons of the edges.
Going pregnant with such an idea, I started to read Physics.StackExchange. In this forum doesn't play a role that intensity pattern occurs behind every edge (in the contour of the geometrical shadow) and not only behind slits. Is it a possible point of view that behind a slit with a large enough distance between the edges of this slit occurs the same patterns like behind a single left edge and a single right edge - if we cut out the images of their intensity patterns and stick them together? I'm searching for arguments that this is not possible. This argumentation I need to contradict my idea about quantized field between photons and the surface electrons from one edge or the edges of single, double or multi slits.
That exists a well accepted and established theory about interference of EM radiation I know by myself, there is no need to talk about this fact. But I don't see a mistake in my explanation and need an argument to step away from my theory.
Beside the traditional point of view about interference of EM waves in the slits region even for single photons or electrons I found in the forum some evidence for the distribution pattern as a result of the quantized field of the interacting electrons from the edge(s): "... the electric field component perpendicular to the surface will be discontinuous, because there is electric field normal to the surface from bound surface charges...". This is an answer from @rob. Is this statement adoptable to my point of view?
I see no way to put this in different questions and hope it will be accepted as one question.
