Two slit in a young's double slit experiment is separated by a distance d. The screen distance is D and it is illuminated by a light of wavelength $\lambda$. A point 0 on the screen is $\large\frac{2d}{3} $ distance from the point which is directly in front of one of the slits. How far away is 0 from the central bright fringe.

Question

$(a)\;\frac{d}{2} \\ (b)\;\frac{d}{3} \\ (c)\;2d \\ (d)\;\frac{d}{6} $
