- Types of Spectra and Blackbody Radiation
The Color Science site show what the three main types of spectra look like and provides code for creating them. The color of blackbody radiators is also discussed.

- Vibrating Charges and Electromagnetic Waves
The wave here consists of a wiggling line of electric force which you can think of as being "attached" to the vibrating charge. Notice that it takes a certain time for the wave to move from one particle to the other. This site contains a Java Applet.
