Expert Answer
Since moon is at infinite distance, image is formed on focal point which is at a distance 7.6 m from mirror.
magnitude of magnification = v/u , where v is mirror-to-image distance and u is mirror-to-object distance.
magnitude of magnification = 7.6 / (3.8×108 ) = 20×10-9
image size = 3450×103×20×10-9 = 69×10-3 m = 69 mm
