What are some things that determine the resonant frequency of glass?

the thickness and purity of the glass will determine the rate at which it vibrates. fine crystal usually has resonant frequencies that are easy to hear.

In what region of the electromagnetic spectrum is the resonant frequency of electrons in glass?
I think in the ultraviolet region of the electromagnetic spectrum.
How can we break glass using sound?
when the natural frequency of glass matches with the frequency of sound than glass can be shettered as it is due to the phenomenon of resonance
Can you Break crystal by singing?
Everything resonates at a certain frequency, from tuning forks to buildings to the Earth itself. When a resonant frequency of a particular object is hit, that object with vibrate in sympathy with that frequency. If the frequency is of a high enough amplitude, the vibrations will cause an object to eventually disintegrate. So the answer is YES, if a singer (well trained) directs all of the sound energy through their vocal chords at a piece of crystal and they are singing at the PRECISE frequency that the crystal resonates at, the glass will indeed break. I've seen it with my own eyes. Hope this helps, Dr. Ron
Why does a glass break when a certain sound wave hits it?
The sound wave must match the glass's natural resonating frequency, which means the frequency that it vibrates naturally at, when the glass picks this up, it vibrates with it due to resonance. The glass can vibrate so violently that it shatters.
How do you find the natural frequency of crystal glass?
i dunno but i rele wanna no too. is there such thing that can pick up the frequency or something????
What frequency does a wine glass break?
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.
What is the sound of glass smashing measured in decibels?
It is not so much the volume of the sound as the frequency as well. Sound at the wrong frequency can be played as loud as you like and it will not break the glass. The sound needs to be the same frequency as the resonant frequency of the glass (tap the glass, that note is it's resonant frequency). Once the resonant frequency has been found, it does not take much volume at all, even humans can do it, albeit trained singers (see Mythbusters).
What do you mean by resonance?
Resonant means something vibrates at a given frequency. Usually if you can get an object to resonate at its resonant frequency - it will disintegrate ! For example - if you tap a wine-glass, it 'rings' - that's it's resonant frequency. Now - take a speaker and play the exact frequency through it, while holding it close to the glass - after a few seconds it will shatter because the glass vibrates too fast.
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.
In what region of the electromagnetic spectrum is the resonant frequency of electrons in glass?
I think in the ultraviolet region of the electromagnetic spectrum.
When you tap a glass with a little water in it It has a high pitch when you tap a glass with water filled to the top it has a low pitch why does this happen?
Glass has a natural frequency at which it vibrates, known as its resonant frequency. If you put energy into the substance at its resonant frequency, you will force it to vibrate or resonate (resonance is a forced vibration). So, tapping imparts energy to the glass molecules and causes them to resonate. This motion sets up a wave of vibration traveling through the glass. The vibrating glass causes air molecules to vibrate similarly. The vibrating air molecules are the sound wave that you hear (the frequency or pitch of the sound wave is the same as the resonant frequency of the glass). As the resonant wave moves through the glass, it moves the water molecules with it, creating a wave of water that you can see near the edge of the glass. The dragging water molecules effectively increase the mass (both the water and the glass molecules) and reduce the energy of the wave traveling through the glass. When the energy is reduced, so is the frequency of the wave in the glass, which is reflected in the pitch of the sound wave that you hear. In simpler terms, when you tap a glass with a lot of water in it, there are fewer vibrations because they have more trouble traveling through the higher mass. Thus, the lower pitch.
Has anyone broken a glass with a high enough pitch?
Yes. The pitch doesn't necessarily need to be that high, it just needs to be the resonant frequency of the glass, and very, very loud.
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.
Can sound go so high that it can't break glass?
Its not an issue of "high" but yes, sound can break glass. What it is is an issue of resonance, find the resonant frequency of the specific piece of glass then generate that precise tone, hold it long enough, and pow the glass will break.This is easy to do in a lab using a microphone, amplifier, and speaker. The glass naturally vibrates at its resonant frequency when tapped, say with a pencil. Place the microphone and speaker close to the glass at a right angle. With the microphone on the amplifier input and the speaker on the amplifier output, tap the glass. If done right you should hear the tone get louder and louder as the glass vibrates more and more, then suddenly it will break (you might need to adjust the amplifier gain and try a few times before it works).It can also be done in a lab using a variable audio oscillator, amplifier, and speaker. This works the same as the first case, except you will have to sweep the oscillator frequency to find and lock onto the resonant frequency of the glass.For the human voice to do it is harder, but some trained professional singers can and have done it by sweeping their frequency until they hear the glass respond, then holding that note until the glass breaks.
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.
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.
Why would music cause glass windows to break in an enclosed room?
depending on the volume the vibrations caused by sound waves will constently be hitting the glass an extreamly high volume would create waves powerfull enough to brake the glass. Everything object has a frequency(resonant frequency), if this frequency is matched and amplifide the vibration can become greater then the object can handle and breaks. On Mythbusters the did this with a wine clas and the got a steel bridge to vibrate trough out its length. but any how it has to do with vibration
