Chladni plates formulas

WebIn the 18th century, Ernst Chladni employed a bow to excite a thin plate, and used small particles to visualize the nodal lines of the resonance [1,2], as shown in Figure 1a.Chladni’s work is the first real attempt to explore acoustic properties through experiments [3,4,5,6].The resonant modes excited by a bow are usually the eigenmodes of the plate. Chladni's law, named after Ernst Chladni, relates the frequency of modes of vibration for flat circular surfaces with fixed center as a function of the numbers m of diametric (linear) nodes and n of radial (circular) nodes. It is stated as the equation where C and p are coefficients which depend on the properties of the plate.
