Expert Answer:

The experiment of scattering of electron form nickel crystal showed that at certain angles there was a peak in the intensity of the scattered electron beam. This peak indicated wave behavior for the electrons, and could be interpreted by the Bragg law to give values for the lattice spacing in the nickel crystal.
The experimental data , reproduced by  Davisson's experiment, shows repeated peaks of scattered electron intensity with increasing accelerating voltage.
This experiment gave the first evidence confirming de Broglie's hypothesis that particles can have wave properties as well.
