    Sometimes I see complementarity explained as being not able to measure any wave and particle property at the same time. But it looks like in a standard double slit experiment the detector measures both particles as the interference, so the wave. The same with a single slit. If a photon is detected outside the centre of the detector, this can only be explained by both particle and wave (diffraction) properties. Of course it is not possible to measure all properties of wave and particle at the same time, but it seems to be possible for some

    Or another question: how can you measure the wave of the photon, without the particle.

    Complimentarity (I think) was really an extended collection of two commuting observables (we have quite a number of them in physics), so just think, uncertainty principle, when you hear that big long word.
