An Opera Singer’s Piercing Voice Can Shatter Glass – Physics suggests that a voice should be able to break glass. Every piece of glass has a natural resonant frequency, the speed at which it will vibrate if bumped or otherwise disturbed by some stimulus, such as a sound wave—as does every other material on Earth. Glass wine goblets are especially resonant because of their hollow tubular shape, which is why they make a pleasant ringing sound when clinked. If a person sings the same tone as that ringing note, a high C in legend but in reality the matching pitch could be any note, the sound of her voice will vibrate the air molecules around the glass at its resonant frequency, causing the glass to start vibrating as well. And if she sings loudly enough, the glass will vibrate itself to smithereens. So in order for a diva to successfully demolish a wine glass, she would have to fortuitously choose one with microscopic defects that are big enough to buckle under pressure singing.
Did you know that In the United States alone there are more than 100 Opera houses? And the number keeps growing as more and more people around the world enjoy the pleasant and emotional impact felt while watching an opera.
One among the oldest and still active opera house is The Teatro di San Carlo in Naples in Europe. The Opera House in Venice Teatro San Cassiano Italy was opened in 1637; the crowds here are both ordinary people as well as the wealthy patrons.
