Free Particle Wavepacket JS Model Documents

Main Document

Free Particle Wavepacket JS Model 

written by Wolfgang Christian

The Free Particle Wavepacket JavaScript model displays the time evolution of a free (V = 0 everywhere) initial Gaussian wave packet in position and momentum space.  The default wave functions have = 0 and

= 0, respectively.  The initial width of the position-space wavepacket can be changed with the slider.

You can modify this simulation if you have Easy Java/JavaScript Simulations (EjsS) version 5.2 or above installed by downloading and importing the zip file into EjsS.
