Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927)
An experiment which conclusively confirmed the wave nature of electrons; diffraction patterns were observed through an electron beam penetrating in a nickel target.
If a particle in periodic motion moves back and forth (or to and fro) over the same path, then its motion it is called as vibratory or oscillatory. The examples of vibratory or osc
