Superpostion is designed to show traveling waves. The superposition applet can animate one or two functions of position and time in separate panels. A third panel can be made available to display the sum of the two functions. Functions should be entered as f(x,t), i.e., 3*cos(3*x+2*t) using the setFunc1(String s) or setFunc2(String s) method.
Superposition is free for non-commercial educational use as outlined in the conditions of use.
