DAVISSON AND GERMER EXPERIMENT
The experiment performed by Davisson and Germer confirmed the De-Broglie hypothesis by demonstrating that electron beams get diffracted when scattered by a crystal.
In this experiment, electrons emerge out of a hole in the form of a fine beam which is then made to fall on a nickel crystal. Electrons are scattered in all direction by the atom of the crystals. The intensity of the electrons scattered in a particular direction is found by detector. By rotating the detector about an axis the intensity of scattered beam can be measured for different angles.
