Answer
Laue Diffraction, named after Max von Laue, occurs when a beam of X-rays interacts with a crystalline material, resulting in the scattering of X-rays in specific directions. This phenomenon arises from the regular arrangement of atoms in a crystal lattice, which acts as a natural grating for the X-rays. The scattered X-rays form distinct patterns, known as Laue patterns, which provide valuable information about the crystal's structure and atomic arrangements.
