where "n" is a positive integer and "λ" is the wavelength of the incident wave. Note that moving particles, including electrons, protons and neutrons, have an associated wavelength called "de Broglie wavelength". A diffraction pattern is obtained by measuring the intensity of scattered waves as a function of scattering angle. Very strong intensities known as Bragg peaks are obtained in the diffraction pattern at the points where the scattering angles satisfy Bragg condition. As mentioned in the introduction, this condition is a special case of the more general Laue equations, and the Laue equations can be shown to reduce to the Bragg condition under additional assumptions.
