Microscope
Useful Tips:
(a) Read your textbook and class notes.
(b) Make sure you understand in-class and textbook examples.
(c) When solving a problem, think whether your steps are reasonable. When answer is obtained,
think whether it makes sense; if not, explain why not and go back to find your errors in reasoning
or/and algebra.
(d) Whenever possible, draw a LARGE diagram to help you solve the problem. It is usually easier to
see triangles and angles on large diagrams. Good luck!
Textbook Reading:
(a) Chapter 36
(b) A nice discussion on the topic of “Eyes and Eyeglasses” can be found in E. Hecht’s textbook
Physics: Algebra and Trigonometry, 2nd edition (Section 24.5, p. 876, Section 24.6, p. 883-887).
This textbook is in the library.
(c) Optical aberrations are discussed very briefly in your textbook. For further discussion, see
Serway’s Physics for Scientists and Engineers, 3rd edition (Section 36.5), where you can find a
short 2-page discussion. This textbook is also in the library. You are, of course, welcome to use
the class notes for your reference.
