Two light waves of wavelengths $\displaystyle 800$ and $\displaystyle 600$ nm are used in Young's double slit experiment to obtain interference fringes on a screen placed $\displaystyle 7$ m away from plane of slits. If the two slits are separated by $\displaystyle 0.35$ mm , then shortest distance from the central bright maximum to the point where the bright fringes of the two wavelength coincide will be $\displaystyle \_\_\_\_$ mm.
