Two wavelengths $\displaystyle \lambda_1$ and $\displaystyle \lambda_2$ are used in Young's double slit experiment. $\displaystyle \lambda_1=450 \mathrm{~nm}$ and $\displaystyle \lambda_2=650 \mathrm{~nm}$. The minimumorder of fringe produced by $\displaystyle \lambda_2$ which overlaps with the fringe produced by $\displaystyle \lambda_1$ is n . The value of n is $\displaystyle \_\_\_\_$.
