The Young's double slit interference experiment is performed using light consisting of $\displaystyle 480$ nm and $\displaystyle 600$ nm wavelengths to form interference patterns. The least number of the bright fringes of $\displaystyle 480$ nm light that are required for the first coincidence with the bright fringes formed by $\displaystyle 600$ nm light is
