Bragg's law is used in XRD to relate repetitive structural size to the diffraction pattern. -Give Bragg's Law.
Bragg's law, a special case of Laue diffraction, gives the angles for coherent and incoherent scattering from a crystal lattice. When X-rays are incident on an atom, they make the electronic cloud move, as does any electromagnetic wave.
