When the distance separations between the slit and screen is doubled, the angular separation between the fringes in slit diffraction experiment.
- A First increase and then decreases
- B Remains same
- C Increases
- D Decreases
Answer & Solution
Correct Answer
(B) Remains same
Step-by-step Solution
Detailed explanation
Angular separation is \(\theta=\frac{\beta}{D}=\frac{\left(\frac{D \lambda}{d}\right)}{D}=\frac{\lambda}{d}\)
Since \(\theta\) is independent of \(D\), angular separation would remain the same.
Since \(\theta\) is independent of \(D\), angular separation would remain the same.
