| 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 angle n. The angle between an incident x-ray beam and a set of crystal planes for which the secondary radiation displays maximum intensity as a result of constructive interference. [After Sir William Henry Bragg and Sir William Lawrence Bragg.] |
