Abstract :
The main purpose of the review article is to introduce the Davission–Germer experiment, to prove the wave nature of electrons through the electron diffraction technique. Initially, de-Broglie proposed a theory about the wave nature of the particle. He argued that every particle has a wave character like each wave has a particle character. He made a valid point by saying due to the law of symmetry of nature if the wave has particle nature, then there must be the particle having wave character. Many scientists tried to prove the above statement true but failed. It is the 1st experiment evidence of the wave nature of the particle. In the experiment, it is proved that an electron (particle) has a wavelength which means the electron has a wave character. If it is true, we can say that radiation has a dual nature i.e., wave and particle. Special attention has been given to the experimental set-up, especially, the scattering of electrons from the nickel crystal, the position of the electron detector, mathematical calculation, and graphical interpretation.
