A two-component beam of light, consisting only of two wavelengths 650 nm and 520 nm, is used to determine interference fringes in a double-slit experiment. The separation between the centers of the slits is 2.43×104 meter and the distance of the plane of the slits from the screen is 720 centimeter. Obtain the smallest angular displacement from the central maximum where the centers of the bright fringes due to the two colors will coincide?
