Why does wine glass make ringing noise?
Wineglass makes lovely sounds when a wet finger rub around its rim. Why does wine glass make a ringing noise? This Science at Home experiment has explained the physics behind it. This physical phenomenon is related to the resonant frequency of glass that is explained details in below in this cool science projects. The new musical instrument of sound is the wine glass. The sound is created with wine glass because of vibrations of the thin glass that makes standing waves of the air inside the glass. When the finger is rubbed around the glass rim, the glass vibrates itself at its resonant frequencies. Because during rubbing the finger, the glass alternately slips and sticks to the finger that results in the formation of glass vibrations at its resonant frequencies. The rapid vibrations of the glass results in the air inside the glass to compress and expand in a regular pattern of the wave. And the wave of air pressure, as well as the vibrations of the air molecules, appears as sound. Do these Physics experiments at home by yourself.
