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

  1. A  \(5 \frac{\lambda}{2}\)
  2. B  \(10 \frac{\lambda}{2}\)
  3. C  \(9 \frac{\lambda}{2}\)
  4. D \(11 \frac{\lambda}{2}\)
Verified Solution

Answer & Solution

Correct Answer

(C)  \(9 \frac{\lambda}{2}\)

Step-by-step Solution

Detailed explanation

Path difference for \(n^{\text {th }}\) minima \(=(2 n-1) \frac{\lambda}{2}\) For fifth minima \((n=5)=\frac{9 \lambda}{2}\)
