optical instruments

[iamsoysauce]

i am wondering about optical instruments. i know this is kind of difficult to illustrate in plain text but i would very much like to see a ray diagram and know where the object, eye, front, back, image and focal lengths are for the following: an eye, a camera, microscope and telescope. also any rules and/or relationships to use with the types of lenses used in these optical instruments(magnification, +/real/inverted and so on). i know. its a tall order cause i write the mcat in 5 days!

It sounds as though you are trying to memorize details for a "thinking" exam. It's true that you need to know the basics, but once you do, then a camera or telescope etc are not necessary for memorization because it falls along the identical basic principles of geometrical optics.

5 days before the exam should be the time to consolidate information and perhaps do 1 or 2 tests and review them in detail. Nonetheless, if you are committed to looking at diagrams of special cases, go to:

If you have access to www.mcatphysics.com, you will learn the basics on online videos in clear language which can be applied to any MCAT optics problem.
