For the double slit experiment with electrons, which one of the following statements is true according to the standard (Copenhagen) interpretation of quantum mechanics? It is possible to measure which slit an electron went through, but if you make this measurement, the beam of electrons will no longer form the multiple fringe pattern on the screen. It is, in principle, possible to measure which slit an electron went through and still see a multiple fringe pattern, if the technology is sophisticated enough. Each electron must have gone through one slit or the other, but it is impossible to measure which slit any one particular electron went through. No answer text provided.
