Reference no: EM13486986

A simple camera telephoto lens consists of two lenses. The objective lens has a focal length f1 = +44.0 cm. Precisely 41.0 cm behind this lens is a concave lens with a focal length f2 =-10.0 cm. The object to be photographed is 4.63 m in front of the objective lens.

(a) How far behind the concave lens should the film be placed?

(b) What is the lateral magnification (ratio of image height to object height) of this lens combination?
