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