In the process of coupled oscillations, energy is transferred between the individual oscillators. This is how waves propagate. Here you can study this with the most simple example of two coupled spring oscillators.
How to use this applet: Drag the two masses to the positions you want them to be in initially, adjust the strength of the coupling between them with the slider on the top, and then click on the START button to watch the time evolution of the system.
