In Young's double slit experiment, a third slit is made in between the double slits. Then
- A intensity of fringes totally disappears
- B only bright light is observed on the screen
- C fringes of unequal width are formed
- D contrast between bright and dark fringes is reduced
Answer & Solution
Correct Answer
(D) contrast between bright and dark fringes is reduced
Step-by-step Solution
Detailed explanation
If a third slit is made between the double slits, then contrast between bright and dark fringes is reduced.
