Monochromatic light of wavelength lamda passes through a very narrow slit S and then strikes a screen placed at a distance D = 1m in which there are two parallel slits S_(1) and S_(2) as shown. Slit S_(1) is directly in line with S while S_(2) is displaced a distance d to one side. The light is detected at point P on a second screen, equidistant from S_(1) and S_(2) When either slit S_(1) or S_(2) is open equal light intensities I are measured at point P. When both slits are open, the intensity is three times as large i.e. 3 I . If the minimum possible wavelength is Nd^(2) , then find the value of N (d lt lt D)

Two ideal slits S_(1) and S_(2) are at a distance d apart, and illuninated by light of wavelength lambda passing through an ideal source slit S placed on the line through S_(2) 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 (dlt lt D)
