Hi folks, This week we did a bit of review for the end of the year and we also spent quite a bit of time looking at how refracting light works. Next week we will primarily be doing review of some of the harder problems of the year and answering any other questions you may have regarding the final exam. There will not be a quiz next week. For homework this week, read chapter 29 in the book. Pages 442 to 459. Do Review Questions # 1 - 26 Best, Jim Mueller (919) 907-3217
