Waves propagating on a string with fixed ends. The string had a length of 0.65 m with c=200 m/s, as would be appropriate for a guitar string. The simulation used the values , and . The initial string profile is given at the top, and successive traces (moving from top to bottom) show the string at progressively later times. For clarity, each trace is shifted downwards from the previous one.

Simulation of a piano string. The string and hammer parameters we used are appropriate for a string near middle C. The string profile is shown at several different times after impact with the hammer.
