| the law that the intensity of a crystal reflection of an x-ray is a function of the angle (Bragg angle) that is the complement of the angle of incidence of the x-ray. |
Bragg's law  (brāgz)  n. The fundamental law of x-ray crystallography, nλ = 2dsinθ, where n is an integer, λ is the wavelength of a beam of x-rays incident on a crystal with lattice planes separated by distance d, and θ is the Bragg angle. [After Sir William Henry Bragg and Sir William Lawrence Bragg.] |
