Well ok, I understand that the full description the underlying physics is given by the Laue equations. But what I don't understand is why does the Bragg condition work at all since it is based on an "unphysical" assumption of reflection. Is there some simple reasoning I am missing why the...

I've been asking myself this question that is not entirely clear to me: the Bragg condition used to describe the constructive interference of waves on a crystal is based on the assumption of reflection. However, x-rays diffract on a crystal rather than reflect, so theoretically there is always...
