WebbX-ray diffraction is determined by Braggs law, which is defined as nλ = 2dsinθ.This law relates wavelength to diffraction angle and the atomic spacing of the lattice within a crystalline sample (known as d-spacing). By using a fixed wavelength (i.e. monochromatic x-ray) the d-spacing can be determined for a specific angle. Rotating either the sample … WebbInternational Science Council Scientific Freedom Policy.
