Hi
I want to add waves with different frequencies and velocities and do a
real time simulation to demonstrate the concept of group and phase
velocity
in physics. Wikipedia has an article here
http://en.wikipedia.org/wiki/Group_velocity
where we can see the simulations for group velocities.
This one (http://en.wikipedia.org/wiki/File:Wave_opposite-group-phase-
velocity.gif) done by user geek3 has a source code in mathematica.
I want to do this in sage. But I should be able to add more than 2
waves and see the simulation. How can I do that ?
See http://sagenb.org/home/pub/3844/ and
http://www.sagemath.org/doc/reference/sage/plot/animate.html
Thanks,
Jason
