Monochromatic light of wavelength λ diffracts through a narrow slit S in an otherwise opaque screen. On the other side of the slit, there is a plane mirror perpendicular to the screen, with a distance h from the slit. A lens is placed at the far end of the mirror, and a viewing screen A is placed at the focal distance of the lens. Light from the slit that travels directly through the lens to A interferes with light from the slit that reflects from the mirror, through the lens to A. This arrangement is known as Lloyd's Mirror, and it produces a double-slit interference pattern from a single slit. 

Are there any phase changes due to reflection?

Monochromatic light of wavelength passes through a very narrow slit S and then strikes a screen in which are two parallel slits, and , as shown in Figure P37.75. Slit is directly in line with S and at a distance of  away from S, whereas is displaced a distance d to one side. The light is detected at point P on a second screen, equidistant from and . When either slit or is open, equal light intensities are measured at point P. When both slits are open, the intensity is three times larger. Find the minimum possible value for the slit separation d.
