The single slite diffraction potential pattern:

A)  central fringe has negligible width then others

B)  all fringes are of same width

C)  central fringes do not exists

D)  none of the above

Correct Answer: D

Solution :

The following diagram indicates a single slit diffraction pattern.                                     As it clear from above diagram, in single slit diffraction, the central fringe has maximum intensity and has width double than other fringes.        So any of the option are not true.
