In a double slit experiment with monochromatic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by $\displaystyle 5 \times 10^{-2} \mathrm{~m}$ towards the slits, the change in fringe width is $\displaystyle 3 \times 10^{-3} \mathrm{~cm}$. If the distance between the slits is $\displaystyle 1$ mm , then the wavelength of the light will be
\_\_\_\_ nm.
