Homework Help: 2 Mirrors and Lenses Problem

  1. Apr 21, 2012 #1
    1. The problem statement, all variables and given/known data
    Two lenses that are L = 34 cm apart are used to form an image, as shown in figure. Lens 1 is converging and has a focal length f1 = 13 cm; lens 2 is diverging and has a focal length f2 = -7.0 cm.
    I am supposed to find out the distance from the first mirror
    2. Relevant equations
    I know how to solve problems with one lens/mirror, but I'm not sure if you have to draw out the rays and extend them to the second lens/mirror to solve it.
    3. The attempt at a solution
    As I said earlier, I am guessing that drawing out the lines will solve it, but now I'm wondering if there is an equation for it.
