1a. A converging lens of focal length 8.07 cm is 20.9 cm to the left of a diverging lens of focal length -6.10 cm. A coin is placed 12.0 cm to the left of the converging lens. Calculate the location of the coin's final image.


It is not -2.32 cm, not 2.32 cm, and not -8.107 cm




1b. Calculate the magnification of the coin's final image.


It is not 0.942, not 0.055, not 0.05535, and not -0.05535
