We emphasized how rays parallel to the principal axis are affected by converging and diverging lenses and mirrors. Also we emphasized how to calculate the critical angle of incidence for two materials through which light travels. You should know what we mean by 'critical angle.'
We examined our lab results from Monday. You will need to prepare the plot of 1/di vs 1/do, and report the focal length you can find for your lens from the equation for the resulting linear fit. You also need to find the focal length from the image produced when an object is at 'infinity.' For both ways of finding f, report the percent error in your focal lengths. We'll turn these in on Monday after the celebration on Thursday. The Senior play is going to be presented tomorrow, and that will affect many of us. Even so, the test will be on Thursday.
