Hi folks,
These websites do a very nice job explaining ray diagrams and how to draw them. There are videos as well.

5/4 Physics update and homework due 5/11
Hi folks,
Today we spent a bit more time working with ray diagrams for lenses and mirrors since the last quiz seemed to indicate that a bit more work with with that concept would be a very good idea. We also introduced static electricity and did a short lab with that. Next week we'll spend more time with that concept.
Next week is our last week to meet other than the final and I'd like to allow time for questions and review. For homework this week, please spend time looking over your old quizzes. Bring any questions you may have to class next week for us all to take a look at. Remember, there are no dumb questions. If you feel uncertain about something, it's almost guaranteed someone else in class has the same issue…and they may not even know it.
Feel free to email me if you need some help as well.
See you all next week.

Physics Final Exam on May 19
Hi folks,
Just a reminder that we have two more classes and then the final exam.
To prepare for the final, I would highly recommend taking a look at all your old quizzes. The final exam will be based on the same material those quizzes were based on. Be sure to go over all questions that you may have missed and be sure to understand them so that you'll be ready for the exam. If you have trouble understanding where you went wrong, there's a good chance the material was covered in a recording and you can also email me if you need help. Feel free to ask questions at the beginning or end of class as well.
I'll provide all formulas and constants so you will not need to worry about memorizing anything.
Good luck everyone!
Never Stop Wondering,
Science Jim
