Here is some info about the second midterm exam. You will be provided with constants from the front of the Hecht book and the moments of inertia from Hecht p. 323. The exam lasts 55 minutes and is an in-class exam on Wed Sep 28 (unless you signed up for the special Tuesday session). The test covers Hecht Ch. 5 to 8 (inclusive), HW #5 to #8 (inclusive), and all the lecture material up to the end of Ch. 8. You may bring in two sheets filled with equations and constants of your choosing for the test. The exam cover sheet has additional instructions, such as bring a calculator, so be sure to read that.
