JEE Physics 2023 Question with Solution

Given: Assertion $A$ states that the beam of electrons shows wave nature and exhibits interference and diffraction. Reason $R$ states that Davisson Germer experimentally verified the wave nature of electrons.

Find: The most appropriate relation between Assertion $A$ and Reason $R$.

Assertion $A$ is correct because electrons do show wave nature and hence can exhibit interference and diffraction.

Reason $R$ is also correct because the Davisson Germer experiment experimentally verified the wave nature of electrons.

Reason $R$ supports Assertion $A$ by providing the experimental verification of the wave nature of electrons.

Therefore, the correct option is C.

The solution states that the beam of electrons exhibits wave-like properties such as interference and diffraction, which confirms Assertion $A$.

It also states that Davisson and Germer's experiment confirmed the wave nature of electrons, so Reason $R$ is correct.

Further, the solution explicitly says that Reason $R$ correctly explains Assertion $A$, and then concludes: So, the correct answer is (C) Both A and R are correct and R is the correct explanation of A.

Hence, based on the solution, the answer is C.
