Bragg diffraction - How to make sense of it ?

  1. Bragg diffraction - How to make sense of it ??

    Is there a way to make sense of Diffraction of X Rays without taking recourse to oversimplified concepts like "Reflection of X Rays by parallel planes" which is generally the explanation in most basic physics books. It's been a couple years since I first studied it and i continue to get confused by assertions like reflecting of Photons by atoms. Online sources are also full of it :

  4. I get that. But, is there a way to explain things without relying on mathematical formalism. I mean a general discussion on the physical mechanism.

    Read chapter two of this dissertation: http://hdl.handle.net/2027.42/63758

    It starts with crystal theory, atomic scattering, and elastic scattering from crystals ... in short, a derivation of diffraction patterns starting from scratch.
