Английская Википедия:Chladni's law
Материал из Онлайн справочника
Шаблон:Short description 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
- <math> f = C (m + 2n)^p </math>
where C and p are coefficients which depend on the properties of the plate.[1]
For flat circular plates, p is roughly 2, but Chladni's law can also be used to describe the vibrations of cymbals, handbells, and church bells in which case p can vary from 1.4 to 2.4.[2] In fact, p can even vary for a single object, depending on which family of modes is being examined.
