Fraunhofer diffraction is observed on a screen placed at a distance of 0.8 m from two parallel slits separated by $0.1 \times 10^{-3}$ m when the slits are illuminated by light of wavelength of $5.46 \times 10^{-7} \mathrm{~m}$ What is the distance of the $3^{rd}$ bight fringe from the cnetral bright fringe?
