Java
Applet by FuKwun Hwang that demonstrates properties of lenses. An
object or the lense can be dragged and dropped and the focus length of
the lense can be varied. Real and virtual images, parameters and traces
are viewed graphically. 

The
most charming example of chromatic dispersion is a rainbow. When white
sunlight is intercepted by a drop of water in the atmosphere. Some of
the light refracts into the drop, reflects from the drop's inner surface,
and then refracts out of the drop. As with the prism, the first
refraction separates the sunlight into its component colors, and the
second refraction increases the separation. And the rainbow is there in
the sky. This applet shows the physics of rainbow.(FuKwun Hwang)
