The angular width of the central maximum in a single slit diffraction pattern is $60^o $ . 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  distance $50\ cm$ from the slits. If the observed fringe width is $1\ cm$, what is slit separation distance?.........$\mu m$
