In a Young's double-slit experiment, the slits are 0.5 mm apart and the interference pattern is observed on a screen at a distance of 100 cm from the slits. It is found that the ninth bright fringe on one side of the central bright fringe, is at a distance of 10.5 mm from the second dark fringe lying on the opposite side of central bright fringe.

Answer» In a Young's double-slit experiment, the slits are $0.5 mm$ apart and the interference pattern is observed on a screen at a distance of $100 cm$ from the slits. It is found that the ninth bright fringe on one side of the central bright fringe, is at a distance of $10.5 mm$ from the second dark fringe lying on the opposite side of central bright fringe. The wavelength of the light used is,
