$Electron Diffraction$

When a polycrystalline graphite foil is illuminated by electron, it is diffracted by the various lattice plane within the crystal. This wave property of electron thus proves the de-Broglie's principle i.e. electrons are waves. In the fluorescent screen, the diffraction pattern is observed around a central bright spot. The diffraction patterns formed here satisfy Bragg's law.
