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 remains the same
Correct Answer: C
Solution :
Angular fringe width is the ratio of fringe width to distance of screen from the source ie, \[\theta =\frac{\beta }{D}\] As D is taken large, hence angular fringe width of the central maximum will decrease.You need to login to perform this action.
