Homework Statement
The barrel of a compound microscope is 15 cm in length (distance between lenses). The specimen will be mounted 1.0
cm from the objective, and the eyepiece has a 5.0-cm focal length. Determine the focal length
of the objective lens.
Known: f2=5cm, L=15cm, do1=1cm
Unknown: f1, di1, di2, do2
Homework Equations
1/di+1/do=1/f
The Attempt at a Solution
A. I drew a diagram: I believe di1+do2=L
B. I have the equations:
1/di1+1=f/f1
1/di2+1/do2=1/5
di1+do2=15
I think there is some relation to distances that I'm not seeing.
