Transcribed Image Text: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.
