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.
