Two finite-width slits are illuminated by a parallel beam of light of wavelength 635 nm. The resulting pattern is observed on a screen at a distance of 1.60m from the slits. The central bright diffraction fringe has a width of 4.20 cm. It is observed that the fourth interference maximum on either side is missing.(a) What is the width of each slit? (b) What is the distance between the slits? (c) What other interferencemaxima (if any) are missing? (d) Sketch the intensity as a function of distance from the center of the pattern.(Your sketch should include three bright diffraction fringes, the central one and the first one on either side.)
