Chladni Sound Figures (U2-05-02)

As early as in the 19th century, Chladni investigated potential vibrational modes in two dimensions. Two-dimensional nodes form nodal lines. Chladni had a simple and ingenious idea of how to make those lines visible. For example, we can use a violin bow to make a round glass plate vibrate. Let’s sprinkle the plate with fine powder. If we hold the plate at the appropriate point, we will obtain a so-called Chladni figure. How can this be explained?
