Due Feb 6

1) Read the Chapter on Light (Chapter 14). Come prepared to ask questions.

2) Do these problems: Ch 14: 1-13 except 4 and 11.

3) I had trouble with my gradebook. Those of you that took back your homework, please bring me Harmonic Motion 7 and the Bookwork due on 1/25. (Ah, heck, bring it all.) Excel corrupted my file. I managed to recover most of the data via software and papers I have in the room, but want to check with all of you to make sure I have as many as possilbe. No one will be hurt by it, but I will be (and already am) greatly inconvenienced by this. So, we'll double check what we have on Tues. (I have all of the major grades, so this is just the homework grades, which really don't count for much anyway.)
