A coherent light is incident on two paralle slits S_(1) and S_(2) . At a point P_(1) the frings will be dark if the phase difference between the rays coming from S_(1) and S_(2) is

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)
