Physical Science 20 - Nov 18

Today in Period 2 we did what happened yesterday in Period 3.  We learned about the laws of reflection and the different types of reflection.  As well we started to learn about curved mirrors and some important terms for curved mirrors that will help us understand them better.  This was all covered on slides 22-31.

In period 3, we started to figure out how to draw ray diagrams for curved mirrors and how to find images in a curved mirror.  This involved drawing three separate light rays and having them reflect off of the mirror.  Students read through the instructions on how to draw the diagrams and then worked on Assignment 2.3.  They will get more time tomorrow to continue this.
