In single slit diffraction experiment, when the distance of separation between the slit and screen is doubled, the angular separation between fringes
- A increases.
- B decreases.
- C remains same.
- D first increases and then decreases.
Answer & Solution
Correct Answer
(C) remains same.
Step-by-step Solution
Detailed explanation
Linear width of central maximum \(=\frac{2 \lambda D }{ d }\)
\(\therefore\) Angular width of central maximum \(=\frac{2 \lambda}{d}\)
\(\therefore\) Angular width of central maximum \(=\frac{2 \lambda}{d}\)
