Laue equations

The Laue equations describe the conditions under which X-rays or other waves can diffract when they hit a crystal lattice. They relate the incoming wave vectors to the crystal's lattice vectors, showing that for constructive interference (the bright spots in diffraction patterns), certain geometric relationships must hold true. Essentially, these equations help scientists understand how X-rays interact with the ordered structure of crystals, allowing them to determine the arrangement of atoms within materials, which is crucial in fields like material science and biology for analyzing molecular structures.
