A beam of light consisting of two wavelengths 6500 A and 5200 A is used to obtain interference fringes. The distance between the slits is 2.0 mm and the distance between the plane of the slits and the screen is 120 cm. (a) Find the distance of the third bright fringe on the screen from the central maxima for the wavelength 6500 A.
