In a Young' 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.

In a Young' 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. (A) 5(λ/2) (B) 10(λ/2) (C) 9(λ/2) (D) 11(λ/2)

Path difference for nth minima =(2n - 1) (λ/2) For fifth minima (n = 5) = (9λ/2)

Q. In a Young' 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.

$5 \frac{λ}{2}$

$10 \frac{λ}{2}$

$9 \frac{λ}{2}$

$11 \frac{λ}{2}$

Path difference for $n^{t h}$ minima $= (2 n - 1) \frac{λ}{2}$
For fifth minima $(n = 5) = \frac{9 λ}{2}$
