Information about the final exam:

The final will consist of 4 questions (to be answered), 3 of which will be on the most recently discussed material (optics and modern physics).

There will also be a question on electricity and magnetism.

This question will focus EITHER on static electric fields, potentials and Gauss's law in electrostatics
OR magnetic fields and forces, Faraday's law and simple (AC and DC) circuits. If you need sample questions,
go through your previous exams 1,2 and 3.

Everyone will have to take the exam during the scheduled 2 hour period.

Only exceptions will be for those who have written permission from the dean of students office (in Rm. 25A, Wilbur Cross).

I also want to thank the majority of you, who worked hard and tried to understand the physics. I know that for some of you, these concepts are not that easy to comprehend. However, struggling through (and trying to understand) the material will be more helpful than trying to memorize formulae. You are welcome to come and see me during this final week (by appointment), if you have any questions (5/15/00).

I was originally planning to put up your final grades on the web. However, (even with the last 5 digits of your id) until some issues on confidentiality are clarified, I may not be able to do that. If you need to find out your grade, please send me an e-mail with your student ID number (5/23/00).

A few comments about the final:

Whenever you draw a ray diagram, remember that light has to travel to the eye of the observer (not the other way around).

Some of you had this direction wrong!!! Think about it. The way you see an object is due to the light coming from it.

Also, some of you couldn't identify the angles of refraction, incidence etc. (and the way light bends when refracted) correctly.
