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.
Draw a picture of a moving source and the waves surrounding it according to what you observed in this experiment. How does the spacing of the wave-fronts in front of the source com
