"Hi Jodina,

The following is from Wikipedia:
"Chladni's lawFrom Wikipedia, the free encyclopediaJump to: navigation, searchChladni's law, named after Ernst Chladni, relates the frequency of modes of vibration for flat circular surfaces with fixed center as a function of thenumbers m of diametric (linear) nodes and n of radial (circular) nodes. It is stated as the equation    f = C (m + 2n)^p where C and p are coefficients which depend on the properties of the plate.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. In fact, p can even vary for a single object, depending on which family of modes is being examined."

I was wondering if you know some values for the coefficient C, or can direct me, please? Actually, I guess what I am really after are some looks at the equation for various patterns -- on a flat circular plate would be great -- in water would be tremendous!! ...."

 

If anyone here at the school has a good answer or lead on this, reply to this post!

Thanks,
