In Young's double slit experiment, the slits are 3mm apart and are illuminated by light of two wavelengths 3750Å and 7500Å. The screen is placed at 4m from the slits. The minimum distance from the common central bright fringe on the screen at which the bright fringe of one interference pattern due to one wavelength coincide with the bright fringe of the other is
