- \(\dfrac{\lambda}{a}\)
- \(\dfrac{2\lambda}{a}\)
- \(\dfrac{3\lambda}{2a}\)
- \(\dfrac{\lambda}{2a}\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: First minima occurs when: \[ a\sin\theta=\lambda \]
Step 2: For small angles: \[ \theta \approx \frac{\lambda}{a} \]
