Courtois, Matthieu; Guirao, Boris; Fort, Emmanuel – European Journal of Physics, 2008
It is well known that the pitch of the sound produced by an excited glass shell can be tuned by adding some liquid in it. In this paper, it will be proved that the distribution of the liquid inside the shell plays a crucial role in this frequency shift. Thus it provides another way to tune the pitch of the sound by modifying the liquid…
