Reflection and Refraction of Light

A self-checking practice quiz on the reflection and refraction of light for an algebra-based physics course: the law of reflection, refraction and the index of refraction, Snell’s law, total internal reflection, dispersion, and Huygens’ principle. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
