Problem
A thin converging lens of focal length 25.0 cm is positioned 0.50 m to the left of a thin diverging lens of focal length −15.0 cm. A 1.8 cm-tall object stands 0.30 m in front of the converging lens on the common optic axis.
All lenses are ideal and of negligible thickness.
(a) Calculate the distance of the image formed by the converging lens from that lens.
(b) Determine the position of this image relative to the diverging lens.
(c) Compute the final image distance measured from the diverging lens.
(d) Determine the overall linear magnification of the system and the final image height, expressing the height in scientific notation with two significant figures.
(e) State whether the final image is upright or inverted and whether it is real or virtual, providing justification for each conclusion.
