Final Exam
Here is the distribution of raw scores for the final exam. While the distribution resembles (again) a nice Bell curve, the average is a bit too low. So, it appears that my original plan for treating one of the five problems as an extra credit problem is a very reasonable one to implement. That would make the perfect score of this exam 40, not 50. BTW, please note that forum activities beyond today will not be considered for credit.
What to bring: your supercomputer (AKA brain), well rested and well greased, 3 crib sheets stapled together, pencils/pens, simple calculator, and (optionally) some drink. What not to bring: everything else.
- The final exam will emphasize diffraction/interference and polarization slightly in the final exam, but you might feel that everything that we covered is treated more or less equally. Fluids and statics will be included, but they will not be emphasized.
- Practice exam problems: Go to forum (the "SQ" link above) to find solutions (by you!). Some solutions may be provided late Wednesday for tricky problems.

Review sheet 3. Also, see Review sheet 1 and Review sheet 2. Let me know if you find any bugs! You can bring three sheets of cribsheets, stapled together, to the final exam.

Some more materials for your review, from your MSI TA: Thanks, Eric!!
Here is the distribution of scores for the midterm 1. The average is about 58 %, which is OK, but not great. The distribution is almost like a bell curve, but it appears to have a slight bulge at 11 and also another weaker bulge at 17 or 18. I am a bit worried about the points 11 and below. Points 17 and above could be roughly regarded as the A range (i.e., A- or higher), I think, if only this exam is to be looked at.
Looking for the old reading-quiz links? Just click "RQ" near the top.
Addition: Some more materials in pages 12-14. Also, please note the use of $I_R$ in describing the intensity of diffraction grating (instead of $I_0$, as in lecture). – 6:28PM, Mar 04, 2013.
Update: This lecture note has gone through a serious proof reading. Two sign errors were corrected, and many small changes were made throughout the text. Update highly recommended! Also, please find and report bugs! – 7:24PM, Mar 03, 2013
