Today we started to look at the property of refraction. This is the property where light bends as it enters a new substance. This bending is due the the fact that light will change speeds as it enters a new substance. This change is speed is due to the optical density of the substance and related by a quantity called an index of refraction. We covered slides 41-48 on the powerpoint and then students were tasked with doing Part A of the Refraction Practice Worksheet. We will go over this tomorrow.
Students handed in Assignment 2.3 today as well. If you didn't hand it in, please do so tomorrow.
