where m is the Bragg order (a positive integer), λ B the diffracted wavelength, Λ the fringe spacing of the grating, θ the angle between the incident beam and the normal (N) of the entrance surface and φ the angle between the normal and the grating vector (K G). Radiation that does not match Bragg's law will pass through the VBG undiffracted.

[3] [4] Wulff was one of the first to experiment with X-ray crystallography. He developed a relationship in X-ray diffraction (nλ = 2d sin θ) which was also found independently by the Bragg father and son duo in 1913 and sometimes called the Bragg–Wulff equation. The mineral wulffite are named after him. [5] [6] [7] [8]

After Trinity, Bragg went to Harvard College and then to Harvard Law School. There he served as the editor of the Harvard Civil Rights-Civil Liberties Law Review, which bills itself as “the ...
Wulff construction. The surface free energy is shown in red, with in black normals to lines from the origin to .The inner envelope is the Wulff shape, shown in blue. The Wulff construction is a method to determine the equilibrium shape of a droplet or crystal of fixed volume inside a separate phase (usually its saturated solution or vapor).
