Question

Explain Davisson and Germer experiment.

Answer 1

• 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.
