What happens if the screen in young's double slit experiment is replac

    What happens if the screen in young's double slit experiment is replaced with a photoelectric material?
    Electrons should be emitted only from regions where constructive interference occurs! Doesn't that mean in this case light will depic both wave and particle nature? That is clearly not possible.
    Where am I wrong?

    Anytime that light (a photon) is absorbed, you might say that the particle nature of light is evidenced. You don't need a photoelectric setup to say that.

    So the two things aren't mutually exclusive?

    You will find that it comes down to a matter of interpretation. There is nothing about the idea that violates any quantum mechanical rules.

    Despite repeated claims in the popular-science literature there's no wave-particle duality in modern QED, and the photoelectric effect does not prove the quantum nature of the em. field. It's described very well as the interaction of quantized electrons bound in the metal with a classical em. wave.

    Could you please suggest me a reference so I can read more about it?

    The photo effect is treated in many modern books about quantum mechanics in the chapter on time-dependent perturbation theory, e.g., in

    Landau, Lifshitz, Course on Theoretical Physics III, Quantum Mechanics.
