A double slit interference experiment performed with a light of wavelength $\displaystyle 600$ nm forms an interference fringe pattern on a screen with 10th bright fringe having its centre at a distance of $\displaystyle 10$ mm from the central maximum. Distance of the centre of the same $\displaystyle 10$ th bright fringe from the central maximum when the source of light is replaced by another source of wavelength $\displaystyle 660$ nm would be $\displaystyle \_\_\_\_$ mm.
