### Refraction and Lenses Videos

On this page, I have links to your Notes as a screencast.  When possible, I have included links to outside sources that also explain the concepts very well.

#### Snell's Law

In this video I discuss Snell's Law and solve a Snell's Law problem.

#### Refraction

In this video I discuss refraction.

In this video I discuss how mirages and rainbows are formed.

#### Convex Lenses

In this video I discuss Convex Lenses.

#### Concave Lenses

In this video I discuss Concave Lenses.

#### Thin Lens Equation

In this video I show you how to solve problems using the thin lens equation.

#### Magnification

In this video I solve for the magnification.

In this video I show you how to draw ray diagrams.
