Two ideal slits S1 and S2 are at a distance d apart, and illuninated by light of wavelength λ passing through an ideal source slit S placed on the line through S2 as shown. The distance between the planes of slits and the source slit is D.A screen is held at a distance D from the plane of the slits. The minimum value of d for which there is darkness at O is
