(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You've been asked to build a 14X microscope from a 2X magnifying lens and a 5X magnifying lens.

What will be the tube length of your microscope?

2. Relevant equations

Meye = 25/feye

Mobj = -L/fobj

M = (Meye)(Mobj)

3. The attempt at a solution

First, are you supposed to use the 5X as the objective? That's what I assumed since it's a higher power, but I'm not sure why exactly?

Then I'm not quite sure what to do next. I found the feye value to be 12.5 cm. But I get don't know what to do after that. If someone could just point me in the right direction I'd appreciate it! Thanks!
