Can teacher explain the experiment using hole any different from pin hole camera? From the image getting at the film the image is upside down. So the light source has been twisted so the theory of test is totally out of logic! If you have double vision or light imbalance problem that is because the material of the barrier and hole and the thickness of the barrier problem I think
QM probability wave function is same with gap of zero of zeta function 1-sin(x)/x, KE-PE=0 from least action which both QM,GR obey, correspond to +,- for odd, even number factor of nature positive integer.
