Glass Shattering Experiment

Did you know you can shatter a wine glass using only sound? In this video, Museum Educator Emily explains how you can measure the unique sound produced by a glass’s vibration, and that sound is called its resonant frequency. If you play a sound that matches the glass’s resonant frequency, the glass will vibrate. And if you play that sound loudly enough, those vibrations will become so intense that the glass shatters!

Something poetic about this, a glass break by its own voice. Be nice to yourself

[scratchpad]

As an interesting side note, it turns out that the bleep used to censor strong profanity on TV and radio shows, which was set at 1 kHz, is very close to the resonant frequency of a wine glass.

glass: ow that hertz
edit: im famous hehehehe

I thought about bridges somehow.
I know that every bridge has a specific vulnerability to a particular wind. The length of the frequency of the waves, is determined by the structure of the bridge. Engineers consider that points when planning.
I also know that in this situation, due to the location of the experiment, which is a chamber, sound waves are actually a movement of the medium, that is actually air, in other terminology, wind!
so maybe in addition to the volume that defined by the size of the amplitude, the measurement that would make the glass break is hight of the tone, that depends upon the frequency of the sound. So every glass has its own breaking frequency, that is belongs to its structure type.

As I understand it it's about accumulation of energy. At other frequencies the sound energy can discipate. It's king of like pushing a swing always at the exact time it's coming down. It always adds a little more energy to the system until it breaks.

We measure EXACT frequency which is ABOUT 1012Hz. Marvelous

[PandP]

Every material has a natural frequency and when we go beyond that resonance occurs

[GRgamingpvz]

This is so true👍🏻
Nicely explained the resonance

[conabe]

This stuff is so cool! Every time I see one of these I get more and more tempted to hop in the car and drive to Boston

[scottishmapping]

Sitting watching YouTube I learn more than school

[junaidshaik]

No shouting, no theatrics, all beautifully explained

[Shuvo-rmfx]

Exact resonanace frequency can break glass or more than the resonance frequency?

[thredstoneman]

This is super cool! What app are you using to measure the frequency of the wine glass?

[sparkyheberling]

What shape does the glass object need to have—or does every piece of glass have a resonant frequency?

[bloxy]

thats why a pc crashed after playing a specific song

[funshorteditz]

we also can change the frequency of this wine glass by adding water

[etherean]

I did understand then I researched and understood.

How I think it could have been explained to help ME understand. Not a criticism of the educator in general coz I'm sure others understood. Writing tus for those who got lost:

Increasing loudness means increasing amplitude of the wave to give the vibration more energy. The frequency is independent to the sound.

So if you have the resonant frequency but with really high energy/amplitude it breaks...

[l_z]

Well critical resonance frequency / vibration point theory there 😊

[cursory]

Glass vibed so much that it shattered by itself

[BashirOjobile]

Sound is a form of energy so energy at work 😊
