X-ray Crystallography: A technique that uses the diffraction of X-rays to determine the three-dimensional structure of molecules and materials at the atomic level.
Bragg's Law: The fundamental equation (nλ = 2d sin(θ)) that relates the wavelength of X-rays, the spacing of crystal planes, and the angles of diffraction.
Atomic Lattice: The regular, repeating three-dimensional arrangement of atoms or ions within a crystalline solid.
Constructive Interference: When waves combine in such a way that their amplitudes add up, resulting in a wave of greater amplitude.
