How Do You Complete a Ray Diagram for an Optical Microscope?

[asdf1]

Homework Statement

For an optical microscope, complete a ray diagram for an objective lens and relate the relate the relative distances to the lens equations. If you want to increase the magnification, should the objective lens have a shorted or longer focal length (illustrate this on the same figure in a different color)?

Homework Equations

lens equation:
1/u +1/v=1/f

The Attempt at a Solution

For an optical microscope, there are 2 converging objective lens. One will have a virtual image, and one will have a real image. In that case, which objective lens is the one that the question wants?
