Water and Frequency of a Tapped Wine Glass

Abstract

The effect of the height of water in a cylindrical wine glass on the frequency when tapped was investigated. The conditions with water inside, outside, and on both sides of the glass wall, were tested for water heights ranging from no water to nearly the top of the glass. The relative effect of each of the three conditions on the frequency followed that predicted by Chen. 1The results for each of the three conditions were also shown to follow the model proposed by French 2for water heights up to 85% full.
