Wavelength Dependence of Interference Fringes

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