33.3 Electron Diffraction
The confirmation of de Broglie's hypothesis of matter- waves and hence that of wave particle duality for matter was provided by Davisson-Germer's experiment on electron diffraction.
Figure 2 The scattered electron beam was found to have maxima and minima
of intensity depending on electron energy for discrete scattering
angles instead of continuous variation of intensity with an angle.
This could be explained only as the consequence of diffraction of
matter- waves associated with electrons. The wave length of these
waves were determined from observation from calculations using l
