In Young's double-slit experiment, the slits are separated by and the screen is placed at a distance of away from the slits. The distance between central bright fringe and fifth dark fringe is measured to be . Calculate the wavelength of light used. Also find the fringe width is the screen is moved towards the slits, for the same experimental setup.
