ELECTRON DIFFRACTION
DescriptionExp-1 Measuring the diameters of the two diffraction rings for different accelerator voltages.
Exp-2 Determining the wavelength of the electrons for different accelerator voltages by applying the Bragg condition.
Exp-3 Confirming the de Broglie equation for the wavelength.
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.
