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
Concept. Davisson and Germer observed electron diffraction from a nickel crystal.
Step 1. Check. Diffraction is a wave property, so both are true and II explains why the experiment shows wave nature.
Answer. Statement I is true, Statement II is true; Statement II is a correct explanation of Statement I (Option A).
