Consider the situation shown in Fig. The two slits S 1 and S 2 placed symmetrically around the central line are illuminated by monochromatic light of wavelength λ. The separation between the slit is d. The light transmitted by the slits falls on a screen S 0 placed at a distance D from the slits. The slit S 3 is at the central line and the slit S 4 is at a distance z from S3 Another screen Sc is placed a further distance D away from S c Find the ratio of the maximum to minimum intensity observed on S c If $z=\frac{\lambda D}{2d}$
