Mid-term grades / My absence next week

Your mid-term grades will be posted tomorrow. As mentioned earlier, for the first time I must post grades for all students in 100 level courses, not just freshman. Sorry! To a large degree, your grade will be dominated by your score on Exam I. See the course information for information on what everything is worth. Ask me during the lab period tomorrow or afterward if you are curious about your grade to date.

And, FYI, I will be out of town (at a conference) from the afternoon of 16 Oct until 20 Oct, though I will be accessible by email. This means I will miss the class on 18 Oct, in which you will learn all about EM waves and start with optics. In my absence, there will be a lab as usual, and the lecture will be given by one of my colleagues.

Lab procedure 9 Oct 2007

Here you are.

This one should work fairly well, or at least it just did for me.

A few bits of advice:

• familiarize yourself with the function generator and voltmeter
• ask for assistance right away if you are not sure what everything does
• make sure you know the difference between the "primary" and "pickup" coils
• always, always be careful which units you use
