Total Internal Reflection

Total Internal Reflection

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection. Use this simple activity as a demonstration or group activity to explore reflection, refraction, fiber optics, and Snell's Law. This resource contains background information about total internal reflection, the equation for Snell's Law, and refractive indexes as well as links to articles about reflection and refraction of light.
