<p>In my book’s chapter about refraction and lenses, there’s the section on Thin-Lens Equation and Magnification Equation and six more sections on specific lenses:
Lenses in Combination
The Human Eye
Angular Magnification and the Magnifying Glass
The Compound Microsope
the Telescope
and Lens Aberrations</p>
<p>My prep book (PR) talks only about the section on thin-lens equation and what not but none of the other stuff. Would it be worth my time to go through those sections? Even though they would be interesting to look at, I’m not sure if they’d be on the test and I’m kinda short on time. Thanks for any help</p>
