How are rainbows formed? Why do they only occur when the sun is behind the observer? If the sun is low on the horizon, at what angle in the sky should we expect to see a rainbow?
This lab helps to answer these and other questions by examining a mathematical model of light passing through a water droplet.
Support for the Curriculum Initiative Project at the University of Minnesota has been provided by a grant from the National Science Foundation (DUE 9456095) and by the Geometry Center.
