Q75 / 90 · JEE Main 2022 (25 Jun Shift 1) · Physics

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
    A
    Both Statement I and Statement II are true.
  • B
    Both Statement I and Statement II are false.
  • C
    Statement I is true but Statement II is false.
  • D
    Statement I is false but Statement II is true.

Solution

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.

Hence, the correct answer is option: 'A'.
