I looked at that "double slit" experiment and for some time now I could not even figure out how anyone could get caught up in such a thing. However in all fairness I realize now that teachers have not been teaching real basics.
Most kids today do not know that light on a bright day, entering a dark room through a slit like in a window shade, inverts the actual picture of the outdoors on a dark wall. Just like a camera lens or even a magnifying glass can do. Most people that use a magnifying glass do not even realize that it inverts objects like overhead lighting when you place the magnifying glass between the overhead lighting several feet above, and a piece of paper below the magnifying glass. You get an inverted image of the lighting. Well the same is true of light through a slit. The way the slit creates an inverted image is by the edges of the slit knocking out the light that would create a correctly oriented picture, and only allowing the particles of light through the slit that enter on an angle. The particles that enter in on an angle create an inverted image.
Even the lasers they use to do the slit experiment are larger than the slits. Which is why you get those effects.
Sincerely,
William McCormick
