Water Depth and Frequency of a Jingdezhen Bowl
by Thirada Boonrawd
Abstract
The relationship between the resonant frequency and water level in a Jingdezhen porcelain bowl was investigated for the first two modes of resonance. The range of water levels studied was between 0 and 39 mm below the rim. It was found that the non-cylindrical bowl can be modeled by an equation originally derived for cylindrical wine glasses for both the first and second resonance modes.
