Bragg X-ray spectrometer, England, 1910-1926 Developed by William Henry Bragg (1862-1942), a professor of physics based in Leeds, England, this X-ray spectrometer was used by him and his son William Lawrence Bragg (1890-1971) to investigate the structure of crystals. The Braggs developed new tools and techniques to understand crystals.
The father-and-son scientific team of William Lawrence Bragg and William Henry Bragg, who were 1915 Nobel Prize Winners, were the original pioneers in developing X-ray emission spectroscopy. [2] An example of a spectrometer developed by William Henry Bragg , which was used by both father and son to investigate the structure of crystals, can be ...
The angles that Bragg's law predicts are still approximately right, but in general there is a lattice of spots which are close to projections of the reciprocal lattice that is at right angles to the direction of the electron beam. (In contrast, Bragg's law predicts that only one or perhaps two would be present, not simultaneously tens to hundreds.)
According to Bragg's law, when an X-ray beam of wavelength "λ" strikes the surface of a crystal at an angle "Θ" and the crystal has atomic lattice planes a distance "d" apart, then constructive interference will result in a beam of diffracted x-rays that will be emitted from the crystal at angle "Θ" if nλ = 2d sin Θ, where n is an integer.

Sir William Henry Bragg (2 July 1862 – 12 March 1942) was an English physicist, chemist, mathematician, and active sportsman who uniquely [1] shared a Nobel Prize with his son Lawrence Bragg – the 1915 Nobel Prize in Physics: "for their services in the analysis of crystal structure by means of X-rays".
