Lecture on Diffraction
*In 1812, von Laue postulated that if crystals were composed of regularly spaced atoms which might act as scattering centers for x-rays (considered to be EM radiation of wavelength roughly the same as the interatomic spacing between crystal planes), then it should be possible to diffract x-rays using crystals
*X-rays diffracted by the crystal (copper sulfate) to form a pattern of spots on a photographic plate W.H. Bragg and W.L. Bragg successfully analyzed the results of the Laue experiment and came up with the mathematical equation for the condition for diffraction
