NEET · Physics · STD 12 - 10. Wave optics
In a Young's double slit experiment if there is no initial phase difference between the light from the two slits, a point on the screen corresponding to the fifth minimum has path difference
- A \(5 \frac{\lambda}{2}\)
- B \(10 \frac{\lambda}{2}\)
- C \(9 \frac{\lambda}{2}\)
- D \(11 \frac{\lambda}{2}\)
Answer & Solution
Correct Answer
(C) \(9 \frac{\lambda}{2}\)
Step-by-step Solution
Detailed explanation
