In an interference experiment using a monochromatic source emitting light of wavelength A = 600 nm, the fringes are produced by two long, narrow slits separated by a distance d mm. The fringes are formed on a screen which is situated at a distance 8.1 m from the slits. Determine d, if the fringe width w = 6 mm. Give you answer in millimetres.
