9. Interference rings ar obtained on the screen placed in the focal plane of a lens (see Figure b). The focal length is f. The light beam used to build the interference image is due to light beam from the source S which is reflected from a glass plate with thickness d. No direct light from S fall onto the screen. Find the radius r of the first dark interference ring, if the center of the interference image is dark as well. (b) Interference setup
