A graph is plotted between the fringe-width (z) and the distance (D) between the slit and eye-piece, keeping other adjustment same. The correct graph is

- A (B)
- B (A)
- C (C)
- D (D)
Answer & Solution
Correct Answer
(C) (C)
Step-by-step Solution
Detailed explanation
(A)
\(z=\frac{\lambda D}{d} \quad \therefore z \propto D .\)
