Two Thin Lenses,one a Convex Lens and the Other a Concave

question 21

Short Answer

Two thin lenses,one a convex lens and the other a concave lens,are separated by 1.00 m along the same principal axis,as shown in the figure.The magnitude of the focal length of the convex lens is 25 cm,while the magnitude of the focal length of the concave lens is 40 cm.An object 8.25 cm tall is placed 35 cm to the left of the convex lens.
(a)Where is the final image produced by this combination of lenses? (Give your answer relative to the diverging lens.)
(b)Compared to the object,is the final image upright or inverted? Is it real or virtual?
