In Young's double slit experiment, the slits are $\displaystyle 2$ mm apart and are illuminated by photons of two wavelengths $\displaystyle \lambda_1=12000 \AA$ and $\displaystyle \lambda_2=10000 \AA$. At what minimum distance from the common central bright fringe on the screen $\displaystyle 2$ m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other ?
Official answer
(2)
$\displaystyle 6$ mm
