In a Young's double slit experiment, if the slit separation is twice the wavelength of light used, then the maximum number of interference maxima is
- A 0
- B 3
- C 5
- D 7
Answer & Solution
Correct Answer
(C) 5
Step-by-step Solution
Detailed explanation
For possible interference maxima on the screen the condition is \(\begin{aligned} d \sin \theta & =n \lambda \quad \ldots (i) \\ \text{Here, } d & =2 \lambda \text { (Given) } \\ 2 \lambda \sin \theta & =n \lambda \\ 2 \sin \theta & =n \end{aligned}\) The maximum value of…
