Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
**Assertion A:** The beam of electrons shows wave nature and exhibits interference and diffraction.
**Reason R:** Davisson Germer experimentally verified the wave nature of electrons.
In the light of the above statements, choose the most appropriate answer from the options given below:
Answer: (D) Both A and R are correct and R is the correct explanation of A
Electron beams do show diffraction and interference (A is correct). The Davisson–Germer experiment observed electron diffraction from a nickel crystal, confirming this wave nature, so R explains A.
