Problem
The Davisson–Germer experiment provided the first direct evidence of the wave nature of electrons.
Answer the following questions related to this experiment:
(i) State the specific experimental observation that convinced physicists that electrons behave as waves.
(ii) Explain, with suitable reasoning, why the appearance of sharply defined intensity maxima at certain angles is inconsistent with a purely particle description of electrons.
(iii) List any two similarities and any two differences between the diffraction pattern obtained with an electron beam and that obtained with X-rays when each is incident on a crystalline target.
