Electron Diffraction

Part of the Series : Experiment: Physics
DVD Price: $49.95



The wave behavior of electrons is studied by measuring the diffraction ring diameters produced when accelerated electrons pass through a graphite lattice. Students record the ring diameters for different electron accelerating voltages. The wavelength of the electrons is directly related to the ring diameters. Students can also verify de Broglie's relation, which states that the electron's wavelength is Planck's constant divided by the electron's momentum since the momentum is proportional to the square root of the accelerating voltage.
