This physics video tutorial on optics provides a basic introduction into ray diagrams. It explains how to draw ray diagrams for converging lens, diverging lens, concave mirrors, and convex mirrors. It explains how to distinguish a real image from a virtual image and how to tell if an image is upright, inverted, enlarged or reduced in size. Law of Reflection - Geometric Optics:
The Mirror Equation:
Refraction of Light:
Snell's Law & Index of Refraction:
Total Internal Reflection & Critical Angle:
Thin Lens Equation:
