This is an activity designed to help students understand geometric properties of rainbows by analyzing the passage of light through a raindrop.  It includes an interactive tool that simulates what happens when rays of sunlight strike a single water droplet.  Users may adjust wavelength and height of up to 5 incoming rays and see the corresponding angles of outgoing rays.  An accompanying problem set gives support to users as they analyze data collected with the simulation tool.  **Note: Some background knowledge in calculus is required.  Recommended for AP Physics courses.

This item is part of a collection of interactive geometry tools and applications.
