Question

why a glass can break because of sound

Answer 1

Answer :

If a singer sings the same musical note that matches the resonant frequency of the glass, the sound waves will vibrate the air particles around the glass at its resonant frequency. ... If a singer sings loudly enough, the vibrations can cause the glass to vibrate so hard that the glass shatters under the strain.

• Every piece of glass has a natural resonant frequency—the speed at which it will vibrate if disturbed by a stimulus, such as a sound wave—as does every other material on Earth. ... When the sound gets too loud for the glass to vibrate, it shatters the glass.
