Physics Summary Chapter 25: Geometric Optics

I'm working through chapter summaries for introductory physics (algebra-based). I'm using the Openstax online (free) textbook College Physics. You can access this book here openstax.org/d...
Here is the playlist with all the videos and problems for this course.

In this chapter:
How we see light and the color black
Law of reflection
Speed of light and the index of refraction
Snell's law
Critical angle
Power and focal length
