The EJS Waveguide model displays the motion of a traveling wave forced to move between two walls in a waveguide.  The two walls are located at y = 0 and a, so that its normal modes are u(t,x) = A sin(n π y/a) cos(k x - ω t) with n equal to a positive integer.  The phase velocity and number of nodes displayed can be changed.  You can modify this simulation if you have Easy Java Simulations (EJS) installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.  

This simulation was created using the EJS modeling tool and is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_ehu_waves_waveguide.jar file will run the program if Java is installed.  Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.  Additional Ejs models for wave motion are available.  They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.
