  1. Dec 15, 2006 #1
    1. The problem statement, all variables and given/known data

    2. An object is placed two focal lengths from a
    diverging lens.
    What type of image forms?
    What is the magnification?
    Where is the image?

    2. Relevant equations

    1/f = (n-1)(1/r1-1/r2)

    3. The attempt at a solution

    a) Virtual Image

    b) m = 1

    c) the image is on the same side as the object with d_i = -2f
