In a Young's double slit experiment, if there is no initial phase-difference between the light from the two slits, a point on the screen corresponding to the fifth minimum has path difference.NEET 2019 (Odisha)

Answer:

Solution:

In a YDSE, the path difference for $n$ th minima is given by $Δ y = (2 n - 1) \frac{λ}{2}$ For 5 th minima, $n = 5$ $∴ Δ y = [2 (5) - 1] \frac{λ}{2} = \frac{9 λ}{2}$
