Hi,

I have been researching about the singing wine glass experiment (EEI). I was wondering where i could find more research papers or information about this equation. I was also wondering what the equation in finding the constant (beta).

Thanks,

I assume you've got A.P. French's original paper?

## 1. What is the A.P French equation?

The A.P French equation is a mathematical formula that describes the relationship between the frequency of a sound produced by a vibrating object and the physical properties of that object, such as its mass and stiffness. It is often used to calculate the natural frequency of resonance in systems such as musical instruments or wine glasses.

## 2. How does the singing wine glass experiment work?

In this experiment, a wine glass is partially filled with water and then rubbed along its rim with a wet finger. This creates friction and causes the glass to vibrate at its natural frequency, producing a sound. As more water is added to the glass, its mass and stiffness change, causing the natural frequency to shift and the sound to change pitch.

## 3. What are the factors that affect the frequency of a singing wine glass?

The frequency of a singing wine glass is affected by three main factors: the mass of the glass, the stiffness of the glass, and the amount of water in the glass. These factors can be manipulated in the experiment to produce different pitches and demonstrate the A.P French equation.

## 4. What is the significance of the singing wine glass experiment?

The singing wine glass experiment is not only a fun and entertaining demonstration, but it also illustrates the principles of resonance and the A.P French equation. This experiment has also been used in the field of acoustics to study the properties of different materials and their effects on sound production.

## 5. How is the A.P French equation used in other fields?

The A.P French equation is used in various fields, including music, engineering, and physics. It is used to understand the behavior of vibrating objects and to design and optimize systems, such as musical instruments or bridges, for maximum efficiency and stability.
