Interference pattern is observed at ' P ' due to superimposition of two rays coming out from a source ' $\displaystyle S$ ' as shown in the figure. The value of ' $\displaystyle l$ ' for which maxima is obtained at 'P' is :
(R is perfect reflecting surface) :
Official answer
(3)
$\displaystyle l=\frac{(2 n-1) \lambda \sqrt{3}}{4(2-\sqrt{3})}$
