Bragg's law is a fundamental principle in the field of crystallography and X-ray diffraction. It relates the angles at which X-rays are diffracted by a crystalline material to the spacing between its atomic planes. The law is named after William Lawrence Bragg and his father, William Henry Bragg, who formulated it in 1913.
