Light Goals

1. What is Light? Be able to describe and give effective examples of the strengths and weaknesses of the two models of light. 2. How does light behave? Reflection: What is the law of reflection? Be able to locate images and make ray diagrams. Refraction: What is refraction? What is Snell’s Law? How did we determine a law for refraction? Be able to solve problems and draw ray diagrams. Colors: What are primary, secondary and complementary colors? How are colors produced by dispersion, add and subtract of light? Lenses: Be able to draw ray diagrams for converging lenses. Identify images as real or virtual. Others: Explain the production the color of the sky and sunset. Summarize how diffraction and interference apply to light.
