emWave.html

Demonstrates how B, E and V (velocity) for an oscillating EM wave dynamically relate.


Raindrops and Dispersion

Fu-Kwun Hwang, National Taiwan University Department of Physics.

~hwang/Rainbow/rainbow.html

Demonstrates how a ray of sunlight is refracted, reflected and dispersed when it strikes a spherical raidrop, producing multiple rainbows. This is an animation of a problem originally solved by Newton in his book Opticks.
