Why can sound break glass?

Sound emitted at a certain frequency can break glass objects due to resonance effect.

Why can sound break glass? Easy to understand, using a hammer? No, it's due to resonance.

The sound that can break glass is due to resonance.

Each object when impacted will vibrate at its natural frequency. If we create sound with a frequency equal to the natural oscillation frequency of an object, it will vibrate. This phenomenon is called resonance .

Each type of glass is made up of different materials. However, they all have natural resonant frequencies. Therefore, when we produce sound that matches their resonant frequency, glass will start to vibrate.

Glass is a fragile material, the bigger the sound, the stronger it vibrates and to a certain extent, glass will break into pieces.
