1. The problem statement, all variables and given/known data A microscope is made in a tube 25.0 cm long. It magnifies 5.00 x 10to the 2 times, 50.0 times by the objective lens and 10.0 times by the eyepiece. What are the focal lengths of the two lenses? 2. Relevant equations m= H/h=-q/p q= p(f) / p-f H= -h(q/p) 3. The attempt at a solution GIVEN m= 5.00 * 10 to the 2 REQUIRED f= focal length = ? cm is what i am trying to find I don't think i have the right equation but i don't know which equation to use.
