In a double-slit experiment, the slit separation is 4.0 × 10-3 m. Monochromatic light of wavelength 500 nm illuminates the two slits and produces an interference pattern on a distant screen. Consider only the fringes on one side of the central maximum. If the linear distance on the screen between the second-order dark fringe and the sixth-order bright fringe is 3.0 × 10-3 m, what is the distance between the slits and the screen.

A converging lens has focal length f.  If an object is placed at a distance between f and 2f from the lens on the principal axis, the image is located at a distance from the lens
