34 A beam of light consisting of two wavelengths 6500 and 5200 is used to obtain interference fringes in a Young s double slit experiment a Find the distance of the third bright fringe on the screen from the central maxima for the wavelength 6500 b What is the least distance from the central maxima where the bright fringes due to both the wavelength coincide The distance between the slits is 2 mm and the distance between the plane of the slits and screen
