Homework Help: Finding Image Distance Relative to the Eyepiece

  1. Oct 29, 2015 #1
    1. The problem statement, all variables and given/known data
    The focal length of the objective lens is 25 mm, that of the eyepiece lens is 73 mm , and the two lenses are 200 mm apart. The object is 30 mm away from the objective lens. What is the image distance relative to the eyepiece lens? What is the overall magnification of this image?

    2. Relevant equations
    No idea.

    3. The attempt at a solution
    I feel as though there is some part of this problem missing. Don't i need the height of the image?
