Physical Science 20 - April 27

 Today in class we went over Homework 2.4 and then started to discover another property of light.  We started examining the property of reflection.  Students did Lab 2.3 on the reflection of light in a plane mirror.  Then we went over the analysis and conclusion to Lab 2.3 which is on the reflection of light.  Students who require help with the analysis can check out this handout.  It has on it all the labels that you need to analyze your lab.  Tomorrow we will continue with the analysis of this lab and then start to talk about the concept of the image.
