    The angular width of the central maximum in a single slit diffraction pattern is 60^(@) . The width of the slit is 1 mu m . The slit is illuminated by monochromatic plane waves. If another slit of same width is made near it, Young’s fringes can be observed on a screen placed at a distance 50 cm from the slits. If the observed fringe width is 1 cm, what is slit separation distance? (i.e. distance between the centres of each slit.)
