The work of Davisson and Germer helped to explain light’s ability to propagate through a vacuum. They designed and built a vacuum apparatus for the purpose of measuring the energies of electrons scattered from a metal surface. Electrons from a heated filament were accelerated by a voltage and allowed to strike the surface of nickel metal.  They observed that at certain angles, there was a peak in the intensity of the scatters electron beam. The peak indicated wave behavior for the electrons.
