^Davisson & Germer experiment

This experiment (1927) established the wave nature of slow moving electrons. In this method a fine beam of accelerated electrons is allowed to strike normally on the nickel crystal and then the intensity of scattered electrons in a given direction is found by using a rotate able detector at various scattering angles. Comparing the wavelength of scattered electrons using Bragg’s law & De – broglie the wave nature of electrons can be confirmed.
