Question:
In Young's double slit experiment, the slits are 2 mm apart and are illuminated by photons of two wavelengths, $λ_1$ =12000 Å and $λ_2$= 10000 Å. At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from one interference patter coincide with a bright fringe from the other?
