A thin, double convex lens having a focal length of magnitude 27.5 cm is placed 1.000 m from a plane mirror that is oriented perpendicular to the principal axis of the lens. A flower, 8.40 cm tall, is1.450 m from the mirror on the principal axis of the lens. (Provide the final image position with respect to the mirror.)
(a) Where is the final image of the flower produced by the lens-omirror combination?(b) If the convex lens is replaced by a double concave lens having a focal length of the same magnitude as the original lens, what will be the answers to part (a)?
