Refraction of light

Summary of the applet The applet demonstrates the refraction and reflection of a light within two different media. The angles are shown on the right column.

Hints and Suggestions A light coming from the top left hits the boundary surface of two media which is possible to choose the substances in both lists. You can vary the incident ray by moving the ray of light into different angles. You can easily understand the 3 different angles; incidence, reflection, refraction, colored in black, blue, red, respectively. "The index of refraction varies slightly for different wavelengths. This phenomenon is called dispersion."

Who Created This Applet. This applet was created by Walter Fendt on December 20, 1997.
