Reflection/refraction probability

  1. Jun 3, 2014 #1
    I was watching Richard Feynman's lectures on quantum electrodynamics where he concerned the probability of photon to be reflected or refracted.

    It is about, that since light incident on a surface is partially reflected and partially refracted, and light consists of photons, then what determines some photons being reflected and some refracted in a monochromatic light incident on a surface of material with different index of refraction.

    Is there an explanation of this phenomena?

    There is no way to choose which photons are reflected/transmitted - nor any way to control it for a given setup.

    This is the basic random aspect of QM which disturbed Albert Einstein ... the only explanation is that that is what QM predicts, and the predictions work.
