A
Diffraction pattern is not observed on the screen in the case of electrons
B
The angular width of the central maximum of the diffraction pattern will increase
C
The angular width of the central maximum will decrease
D
The angular width of the central maximum will be unaffected
Answer
The angular width of the central maximum will decrease
Explanation
Solution
The correct option is (C): The angular width of the central maximum will decrease
