(choose chapter or problem)

Visitors at a science museum are invited to sit in a chair to the right of a full-length diverging lens (f1 5 23.00 m) and observe a friend sitting in a second chair, 2.00 m to the left of the lens. The visitor then presses a button and a converging lens (f2 5 14.00 m) rises from the fl oor to a position 1.60 m to the right of the diverging lens, allowing the visitor to view the friend through both lenses at once. Find (a) the magnifi cation of the friend when viewed through the diverging lens only and (b) the overall magnifi cation of the friend when viewed through both lenses. Be sure to include the algebraic signs (1 or 2) with your answers.
