In a two slits experiment with mono chromatic light fringes are obtained on a screen placed at some distance from the slits. If the screen is moved by 5 \times 10 ^ { - 2 } m towards the slits, the change in the fringe width is 3\times 10 ^ { - 2 }m . If seperation between the slits is 10 ^ { - 2 }m the wavelength of light used is
