- $5\frac{\lambda}{2}$
- $10\frac{\lambda}{2}$
- $9\frac{\lambda}{2}$
- $11\frac{\lambda}{2}$
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Path difference for \(n^{th}\) minima \(=(2n - 1) \frac{\lambda}{2}\)
For fifth minima \((n = 5) = \frac{9\lambda}{2}\)
Therefore, the correct option is (C) : \(9\frac{\lambda}{2}\)
