Reflection+and+Refraction+of+Light+Waves

Click here to see the applet.

Summary: This applet helps you to understand the reflection and the refraction of waves by the //principle of Huygens//.

How to play: Whenever a step is finished, press the "Next step" button! You can stop and continue the simulation by using the "Pause / Resume" button. The three text fields make it possible to vary the index of refraction of both media and the angle of incidence. The medium with the smaller index of refraction (the bigger phase velocity) is painted yellow, the other blue.

Who created this: This applet was created by Walter Fendt on March 5th, 1998.
