Position and momentum of particle in double slit experiment?

    In the double slit experiment, what is the position and momentum of an electron/photon?
    Is the position of the electron/photon which slit it went through? And is the momentum of the electron/photon the wave like interference pattern detected on the detector screen?

    The position is wherever it is first measured. If you have detectors in the slits, then they determine the position at one slit or the other; if not, the position is where the spot appears on the screen behind the barrier.

    The momentum is not measured at all in this experiment.
