Well. Since we have no new homework set next week (due to an impending exam the following week), there is no good reason to make the homework due on Monday. The 9th homework set is now due Wednesday, 2 April at 5pm.
The idea is, of course, to make sure after Wednesday that you have nothing in your way to prevent you from studying for the exam ... the details of which will follow in the coming days.
I added a bit at the end of Ch. 11 about parabolic mirrors, and fixed some nagging typos. You can download a revised set of notes on mirrors here. The linked file contains only the chapter on mirrors.
I hope to have something on lenses posted by the end of tomorrow. By the end of Friday's recitation we will cover enough of the material on lenses for you to complete the homework.
We will spend quite some time on the homework in class Thursday.
Today we will explore reflection and refraction of light. The procedure is very open-ended, intended to be discovery-based.
Here is the procedure, read it through before starting.
Fun with optics. Enjoy.
UPDATE: Problem #9 has been changed. As stated, it was more difficult than I thought ...
