The answer is "it's own resonant frequency".. this frequency is dependent on how the glass is made.
You can hear this frequency when you rim the glass with a wet finger or smack it with a pen.
If you want to break it, place the glass next to a nice speaker, generate a sine-wave tone matching the resonant frequency, and turn it up to 11.

How high does your voice have to be to break glass?
you have to have a very high voice to break a glass and this is what you have to do to break a glass you can break a glass because a glass is very resonant and frequency. and you also can break a glass by holding your high voice for two or three seconds and then the glass breaks. no its impossible for just your plain high voice you have to have a high microphone (with speakers) to break a light wine glass.
What needs to happen for a human voice to break a wine glass?
you need to sing at the right frequency and sing loud enough to resist the vibrations. when the sound gets to loud for the glass to vibrate it shatters.
How do you break glass with music?
If a sound can reach the frequency the glass atoms vibrate at, it can be broken
How does singing break glass?
Singing causes air to vibrate. if the vibration is at the resonant frequency of the glass crystal structure, the structure absorbs the singing Energy. If the singing is intensity is high enough and at the resonance frequency, the crsytal bounds will break and break the glass.
How could you find the sound frequency to break a glass?
High frequency sound waves can shatter glass if powerful enough. This happens because the glass vibrates at the same frequency as the sound waves on the outer surface of the glass, but at lower frequencies inside the glass. This causes interference in the waveforms moving through the glass, which stress the glass, causing it to break. This is a different effect than when a single sharp sound, such as an explosion, pushes the glass beyond its breaking point.
How does glass break with sound?
When a high-intensity sound wave hits glass, it can cause the glass to vibrate at its natural frequency, leading to stress and ultimately causing the glass to break.
What causes the phenomenon of resonance in glass breaking?
Resonance in glass breaking occurs when the frequency of sound waves matches the natural frequency of the glass, causing it to vibrate and eventually break.
Why does a glass break when you reach a certain sound?
A glass can break when exposed to a specific frequency of sound because the sound waves can cause the glass to vibrate at its resonance frequency, leading to a buildup of energy that can exceed the glass's strength and cause it to fracture. This phenomenon is known as acoustic resonance.
Does the size of the wine glass affect how much sound is needed to break it?
Yes.
Do most objects have a natural frequency of vibration?
Absolutely not! Glass, for example (every wine glass has a different natural frequency), can be broken by a frequency that matches its own but nearby objects aren't affected by the same frequency.
How high do you have to be to break glass?
You don't necessarily have to go so high to break a glass, rather it is hitting the exact same frequency of vibration that the glass has. So you would tap the glass to determine the frequency (you need someone with perfect pitch or an analyzer), and then you just have to hit that same note at the right intensity to break the glass.
Can you break a glass by high pitched noises?
Yes, high pitched noises can break glass through a phenomenon called resonance. If the frequency of the sound wave matches the natural frequency of the glass, it can cause the glass to vibrate excessively and eventually shatter. This is why opera singers are sometimes able to shatter glass with their high-pitched voices.
