What Is the Natural Frequency of Glass?

Answer

The natural frequency of glass is the highest pitched tone it produces when taped. This tone is not universal for all glasses but rather depends on the size, shape, thickness and the amount of dumping available on the glass. The natural frequency of a particular glass will make it vibrate and if prolonged can break the glass. The natural frequency of some glasses is 1180 Hz and is also known as resonance.
