Question 23 of 191

Interference pattern is observed at ' P\mathrm{P} ' due to superimposition of two rays coming out from a source ' SS ' as shown in the figure. The value of ' l\mathrm{l} ' for which maxima is obtained at ' P\mathrm{P} ' is:
( R\mathrm{R} is perfect reflecting surface)

Show answer and solution

Answer: (C) 1=(2n−1λ)34(2−3)\left.1=\frac{(2 n-1 \lambda) \sqrt{3}}{4(2-\sqrt{3}}\right)
