 Can sound break glass?


  Every object when struck vibrates at a frequency, natural frequency. If we make sound having a frequency which matches the object's natural frequency, then that object starts to vibrate. This is called as resonance.

  So this way, is it possible to break glass through resonance, through sound? Let's see..

  Every glass is formed from different materials. However, all of them have a natural resonant frequency. Hence, once we make sounds which match their resonant frequencies, the glasses start to vibrate.

  As glass may be a brittle material, louder the sound, more violently will it vibrate causing the glass to shatter into pieces.

  Thus, if we are able to produce sound of high frequency, higher than that of the glass, we can break it with sound.
