double slit experiment with very low intensity , i.e. one photon or atom at a time: get still interference pattern if we wait long enough 24
Double slit experiment – QM interpretation • patterns on screen are result of distribution of photons • no way of anticipating where particular photon will strike • impossible to tell which path photon took – cannot assign specific trajectory to photon • cannot suppose that half went through one slit and half through other • can only predict how photons will be distributed on screen (or over detector(s)) • interference and diffraction are statistical phenomena associated with probability that, in a given experimental setup, a photon will strike a certain point • high probability bright fringes • low probability dark fringes 25
