Refraction and the Ray Model of Light

The ray nature of light is used to explain how light refracts at planar and curved surfaces; Snell's law and refraction principles are used to explain a variety of real-world phenomena; refraction principles are combined with ray diagrams to explain why lenses produce images of objects.

Lesson 2:  The Mathematics of Refraction

Lesson 3:  Total Internal Reflection

Lesson 4:  Interesting Refraction Phenomena

Lesson 5:  Image Formation by Lenses
