Question 135 of 191

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 exhibit 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 :

Show answer and solution

Answer: (D) Both A and R are correct and R is the correct explanation of A

The Davisson-Germer experiment showed that electron beams can undergo diffraction when passed through the atomic crystals. This shows that the wave nature of electrons. When electron is in wave nature it can exhibit interference and show diffraction.
Hence, Both A and R are correct and R is the correct explanation of A.
