detailed solution

Correct option is C

Path difference = x (d /D ) where d is the separation between two sources and D is the distance of screen from two sources. Phase differenceϕ=2πλ×xdD ⇒φ2=πxβIntensity at a distance x from the central bright fringe is given by I = I0 cos2 φ2=I0 cos2 πxβ

In Young's double slit experiment intensity of light emerging from each slit is I₀. Wavelength of light used is $λ$ , separation between the slits is d and separation between the slits and screen is D. P is a point on the screen where the resultant intensity is 3I₀. Then the minimum path difference between rays emerging from the slits at point P is
