One of the key experiments that provided evidence for the wave-particle duality of electrons is the Davisson-Germer experiment. In this experiment, a beam of electrons was directed towards a crystal surface, and the scattered electrons were observed. The result showed a diffraction pattern, similar to what is observed when light waves pass through a narrow slit. This diffraction pattern confirmed the wave-like behaviour of electrons.

Another important experiment is the electron interference experiment, where a beam of electrons was split into two paths and then recombined. Interference fringes were observed, indicating the wave-like nature of electrons. These experiments demonstrated that electrons can exhibit both particle-like and wave-like properties, supporting the concept of wave-particle duality.
