In Young's double slit experiment, a third slit is made in between the double slits. Then,
- A intensity of finges 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
When a third slit is made in between the double slits in YDSE, then contrast between bright and dark fringes is reduced. \(\hat{t}\) is because in the case of double slits, light passes only two slits. Now, the same light is passing through the three slits which results in…
