In Young's double slit experiment, the two slits are separated by a distance of 1.5 mm and the screen is placed 1 m away from the plane of the slits. A beam of light consisting of two wavelengths 650 nm and 520 nm is used to obtain interference fringes. Find (a) the distance of the third bright fringe for λ= 520 nm on the screen from the central maximum. (b) the least distance from the central maximum where the bright fringes due to both the wavelengths coincide.
