Summary

Description

Propagation of a wave packet in a dispersive medium. We can see the difference between phase velocity and group velocity. Made by myself. See also Image:Wave packet (no dispersion).gif.

Therefore, the image is redone based on the equation in Wave_packet#Dispersive. The parameters are k0=7, 0<t<2, -2<x<8. Source: own work License: Creativ...
