Fast moving electrons are diffracted from a polycrystalline layer of graphite. As these particles travel through graphite crystal lattice, interference rings appear on a fluorescent screen. The interplanar spacing in graphite is determined from the diameter of the rings and the accelerating voltage. This illustrates the wave nature of particles and can be used to investigate DeBroglie’s equations and be used to determine the particle wavelength associated with each accelerating voltage. Using the relationship between the radius of the diffraction rings and wavelengths the interplanar spacing can be calculated.
