In Young's double slit experiment the slits are 0.5 mm apart and interference is observed on a screen placed at a distance of 100 cm from the slits. It is found that the 9th bright fringe is at distance 8.835 mm from the second dark fringe from the centre of the fringe pattern. Find the wavelength of light used.
