Dispersion relation
This subject seems to be coming up quite often, especially for those studying wave mechanics.
Here is a brief intro. I'll be looking for better articles and I hope others will contribute references or insight from personal experience. http://en.wikipedia.org/wiki/Dispersion_relation and related topics http://en.wikipedia.org/wiki/Group_velocity http://en.wikipedia.org/wiki/Phase_velocity http://tosio.math.toronto.edu/wiki/i...rsion_relation - note that this is a wiki page from Department of Mathematics at U. Toronto I also hope to address anharmonic and non-linear systems. I think it important for students to understand the significance of the higher order spatial (and temporal) derivates with respect to the dependent variable, uxxx or [itex]\partial^3_x\phi[/itex] in the KdV equation. |
