Lissajous Rods

In this exhibit there are six individual rods, each of which has been cut in a special way. When plucked, each rod vibrates in a unique pattern. They are squared off near the bottom and in some cases are thicker on one side than the other. The ratio of these two thicknesses determines the pattern of the vibration. When a rod is plucked it moves along two different axes and at two different rates to form its special pattern.
