Explain Davisson and Germer experiment.

Answer»
  • The wave nature of electron was experimentally confirmed by Davisson and Germer. 
  • They allowed the accelerated beam of electrons to fall on a nickel crystal and recorded the diffraction pattern. 
  • The resultant diffraction pattern is similar to the X – ray diffraction pattern.
  • The finding of wave nature of electron leads to the development of various experimental ’ techniques such as electron microscope, low energy electron diffraction etc.
