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/details/books/co...
Here is the playlist with all the videos and problems for this course.

Here is the PheT simulator

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
- Thin lenses, real vs. imaginary images
- Magnification
- Mirrors
