Physical Science 20 - May 15

Today students learned about the laws of refraction.  In particular a law called Snell's Law.  This law tells us how the angle of incidence relates to the angle of refraction.  We did a couple of examples where we applied this law.  Students then had the remainder of class to work on Part B of the Refraction Practice Problems.  Students in Period 4 also worked on Assignment 3.1 which was on refraction diagrams.  I will be checking these 2 things on Tuesday for Period 4.  Students in Period 2 will get a little bit more time to work on these.  However, those students are going to be writing a quiz for me on Tuesday. Study Homework 2.2, 2.4 and 2.6!! It is on speed of light, magnification and mirror equation. Period 4 will be writing this quiz on Thursday.
