In YDSE, an interference pattern is obtained for $λ = 6000 \overset{˚}{A}$ , coming from two coherent sources $S_{1}$ and $S_{2}$ . At certain point P on the screen third dark fringe is formed, then the path difference $S_{2} P - S_{1} P$ in micron is :-

Options:

Answer:

Solution:

Third dark fringe: $Δ x = \frac{5 λ}{2}$

$Δ x = \frac{5 \times 0.6 μ m}{2}$

$Δ x = 1.5 μ m$
