Lab 5 - Dispersion

This is a computer simulation lab. The applet was created by Dr. Dallin Durfee (who apparently sometimes calls himself "Dr. Bongo", as you will see if you click the help link below). You can run the applet on any Java-capable computer.

This lab shows how a Gaussian pulse propagates in dispersive and non-dispersive mediums. It also shows the spectrum of a Gaussian pulse. You can change the pulse width, the center wavenumber of the pulse, and the dispersion relation. It can be used to illustrate uncertainty relations, dispersion, and the difference between phase and group velocity.
