Bragg's law
Bragg's law B0445800 (brăgz)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.]Bragg's law n (General Physics) the principle that when a beam of X-rays of wavelength λ enters a crystal, the maximum intensity of the reflected ray occurs when sin θ = nλ/2d, where θ is the complement of the angle of incidence, n is a whole number, and d is the distance between layers of atoms [C20: named after William and Lawrence Bragg]Bragg's law
Bragg's law[′bragz ‚lȯ] (solid-state physics) A statement of the conditions under which a crystal will reflect a beam of x-rays with maximum intensity. Also known as Bragg's equation; Bravais' law. |
