How High does a note have to be to shatter glass?

Question

if it is a myth what is this? http://www.youtube.com/watch?v=j82jeSGIXxU&search=high%20note

Answer 1

I don't think you can shatter just ANY glass with a note.

For a note to shatter crytsal, the note has to match the frequency of said crystal, as well as having an adequate amplitude.

Don't try this with mom's good glasses: if you tap the rim of a wine glass, you'll hear a ring. Match that pitch (or one of it's harmonics) with voice or instrument, and you might be able to break it if you get loud enough.

Answer 2

I think it is E# but I'm not sure. I know it has to be a very high pitch screech and depends on the thickness of the glass. I think it can crack a glass but not shatter it.

Answer 3

Watch Mythbusters, they did it successfully on the show.

It's not how high the note is, it just has to match the resonant frequency of the glass and be loud enough to add too much energy to the glass for it to break.

Answer 4

It's been proven that a high note can not shatter glass. It's an urban myth.

Answer 5

It is very possible for sound to shatter glass
Check out the study done on it at the University of Salford

Answer 6

in case you hit a tumbler along with your fingernail it is going to 'ring' at a definite frequency, referred to as its 'organic' frequency. The frequency has to do with how the glass is made, how heavy that's, how thick that's, and so on. it fairly is particularly slightly glass 'bell'. whilst that frequency is performed by way of a speaker, or sung, the glass will vibrate alongside with it. it fairly is referred to as 'sympathetic vibration'. you're able to do an identical element with a guitar string. in case you play that comparable notice particularly loud on yet another tool and then end unexpectedly, you will pay attention that guitar string vibrating, taking part in the notice. it fairly is variety of like pushing somebody on a swing. you should push on an identical 'frequency' the swing is swinging. you often wait till it comes lower back each and all of the way and provide the swing a push because it is going forward. The swing additionally has a organic frequency. you should push at basically the main suitable suited time. in case you purely pushed at random situations, the swing would not swing. Vibration works an identical way, with waves of air rigidity arriving basically on the main suitable suited time to push the glass or guitar string, so the vibration interior the glass or string gets greater suitable and greater suitable. whilst the glass vibrates strongly adequate it is going to wreck! I even have on no account seen everybody try this with basically their voice. it may take a super variety of capability! They did it on Mythbusters with audio gadget. i assume it may be achieveable to do it along with your voice in case you have been loud adequate, and if the glass grow to be particularly skinny. it fairly is why they use crystal glasses, because of the fact they are thinner and greater well-off.

Answer 8

it depends on the thickness of the glass

Answer 9

Dont know but I've seen it done.
Or was it her breath?

Answer 10

i dont know . go get an oprah singer and find out.
