Bending of light – calculating refraction for surfaces such as water
A variation on reflection is refraction, the bending of light as it passes through a surface, or more accurately, light passing through air into another surface. We see refraction when we observe a straw in a glass of water or view the bottom of a pool. Have a look at the following screenshot:

This won't become a class in physics, I promise. But we cannot ignore it either, and besides, a little physics never hurt anyone (just continue to stay out of the way of falling objects). We need to take a moment and ...
