Solution


Q.

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.            [2023]

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:
1 A is correct but R is not correct  
2 A is not correct but R is correct  
3 Both A and R are correct but R is not the correct explanation of A  
4 Both A and R are correct and R is the correct explanation of A  

Ans.

(4)

Beam of electrons show wave nature and exhibit interference and diffraction as shown by Davisson Germer experiment.
