HW5

is out. Due Tuesday. We'll go over some of these in class on Tuesday if you get stuck.

Left my phone at home ...

so if you need to reach me today (Thurs), email is basically it.

Updated grades

Your exam 2 and homework 3 grades are now available on eLearning. Enjoy, and let me know if anything seems mistaken.

The average for exam 2 was 78.6 with a standard deviation of 14.3. The A/B/C/D/F breakdown was 15/11/10/10/6. I am happy with it overall. More intelligent comments after I've slept a bit.

Thursday's lab

you will do 2 short experiments. First, demonstrating the laws of reflection and refraction, and second, playing with lenses. Print both procedures, you should finish relatively quickly.

There will be a quiz in the lab, on refraction.

HW4 solutions

are here. I don't have a solution typed up for the last problem right now (and it is exceedingly unlikely to happen before the exam), but nothing like it will show up on the exam. Also, I did it all in class today ... if you missed that, you can ask one of your classmates.

Summer 2010 Exam 2

This handwritten solution is as good as it is going to get. The last problem I didn't solve since it isn't relevant to the upcoming exam, and time is running short ...

Summer 2009 exam 2

problem number 4 now has a solution. The original number quoted (without solution) was a factor 2 too high for part a. Part b was fine. 

Exam coverage

I will not ask questions about EM waves, on further reflection (<- you will see the pun after tomorrow's lecture. HA.) That leaves:

in the Knight book, Ch. 23.1-6, 24.1-7, 25.1-4. 

in the Serway book, 18.1-4, 19.3-9, 20.1-6, 21.1-3

or, by topic, dc circuits (multiple battery circuits especially), magnetic fields, induction, ac circuits (filters only, as in notes)

HW6 summer 2010

is relevant to your interests, and I just put up a solution. Must have missed it at the time.

Spring 08 HW6 is also updated to have more or less complete solutions as well.

Grades online

You can now view your grades online through eLearning ... I have grades for HW1-2, Q1-4, L1-4, and Exam 1 posted right now. I won't use eLearning for anything but posting your grades. I don't much like it in general, but it is convenient enough for this purpose.

If somehow you have escaped eLearning until now, consider yourself fortunate. You can access it by going to your Student tab on myBama, it should be a fairly prominent link. Once you're in, it should be easy enough for you to figure out how to find your grades. If you have any trouble, let me know. 

Monday's lab

will be about induced voltages and transformers. There will be a quiz after the lab.

Homework 4 is out

and you can find it here. Sorry for the delay - meant to have it done Friday, but helping my parents move this weekend, among other things, took more time than I planned. Note that it is not due until Tuesday now as a result of my delay.

And, yes, these are excellent problems to study for the upcoming exam. We'll go over most of them in class Mon & Tues.
