Diverging and converging lens

  1. Jan 31, 2012 #1
    1. The problem statement, all variables and given/known data

    A converging lens of focal length 7.740 cm is 19.7 cm to the left of a diverging lens of focal length -5.51 cm. A coin is placed 18.2 cm to the right of the diverging lens

    a. Find the location of the coin's final image.

    b. Find the magnification of the coin's final image.


    2. Relevant equations

    I tried the thin lens equation but that gave the wrong answers. I am not sure as to what equation to use.

    3. The attempt at a solution
