In Young's double slit experiment, the separation between the slits is halved and the distance between the slits and the screen is doubled. The fringe width
- A remains unchanged.
- B becomes half.
- C becomes double.
- D increases four times.
Answer & Solution
Correct Answer
(D) increases four times.
Step-by-step Solution
Detailed explanation
