1. The problem statement, all variables and given/known data 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)? 2. Relevant equations lens equation: 1/u +1/v=1/f 3. 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?
