Interference pattern is observed at '

\mathrm{P}

' due to superimposition of two rays coming out from a source '

S

' as shown in the figure. The value of '

\mathrm{l}

' for which maxima is obtained at '

\mathrm{P}

' is: (

\mathrm{R}

is perfect reflecting surface) Interference pattern is observed at ' P ' due to superimposition of two rays coming out from a source ' S ' as shown in

Options

A $1=\frac{2 n \lambda}{\sqrt{3}-1}$
B $\left.1=\frac{(2 \mathrm{n}-1) \lambda}{2(\sqrt{3}-1}\right)$
C $\left.1=\frac{(2 n-1 \lambda) \sqrt{3}}{4(2-\sqrt{3}}\right)$
D $1=\frac{(2 \mathrm{n}-1) \lambda}{\sqrt{3}-1}$
