Physics Question on Wave optics
In single slit diffraction pattern
A
central fringe has negligible width than others
B
all fringes are of same width
C
central fringes do not exist
D
None of the above
Answer
None of the above
Explanation
Solution
The following diagram shows a single slit diffraction pattern. 
As is clear from above diagram, in single slit diffraction, the central fringe has maximum intensity and has width double then other fringes. Hence, none of the options are true.
