JEE Main 2022 — Dual Nature of Matter Question with Solution

JEE Main 2022 (25 Jun Shift 1)

Question

Given below are two statements :

Statement I : Davisson-Germer experiment establishes the wave nature of electrons.

Statement II : If electrons have wave nature, they can interfere and show diffraction.

In the light of the above statements choose the correct answer from the option given below :

Correct answer
ABoth Statement I and Statement II are true.

Step-by-step explanation

In Davisson–Germer experiment, the high speed electrons are incident on Ni crystal and they get diffracted just like a wave. So wave nature of electron was experimentally observed in this experiment.
