One method of prodocing two in - phase point sources of light for interference is to form two images of a point source by means of the two halves of a lens,which has been split along a diameter[Fig.6.17]. How must the two halves of a 5 cm focal length lens be placed to form two real images sources0.24 cm apart and 20 cm from the source?
