Statement I: Davisson–Germer experiment established the wave nature of electrons.
Statement II: If electrons have wave nature, they can interfere and show diffraction.
Answer: (A) Statement I is true, Statement II is true; Statement II is a correct explanation of Statement I
Davisson and Germer observed a diffraction peak when electrons were scattered from a nickel crystal, which is possible only for waves. Both statements are true, and Statement II explains why the experiment establishes wave nature.
