An optical instrument is built from a converging lens (lens 1) with focal length 15 cm and a diverging lens (lens 2) with a focal length -25 cm. The lenses are placed 20 cm apart. An object is placed 10 cm from lens 1.

(a) (6 points) Compute the final image location of the instrument. Report a distance from lens 2 with the correct sign.

(b) (2 points) Compute the total magnification.

(c) (2 points) Describe the final image (magnification, real or virtual, straight or inverted). Support your description.
