PhysicsSingle correct+4 / -1Question 45 of 90

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 :

Both Statement I and Statement II are true.

Both Statement I and Statement II are false.

Statement I is true but Statement II is false.

Statement I is false but Statement II is true.

Answer and worked solution

Official answer: A

Statement I is true: electron diffraction by a nickel crystal confirmed de Broglie waves.

Statement II is true: anything with wave nature can interfere and diffract (which is exactly what the experiment showed).

(A)

Topics:Davisson-Germer experiment de Broglie waves
