Force of Resonance Frequencies

The resonance frequency of an ordinary Christmas ornament is emitted using a Pasco Function Generator. The frequency yields a small force (millinewtons) on the ornament. However, with this pendulum setup, the force can be observed.

how did you find the frequency?

[XerxesNel]

A microphone was placed in the ornament, which fed into an amplifier, then finally to an oscilloscope, or scope for short. The scope displayed the frequency and I just had to adjust the frequency until a maximum amplitude was observed on the scope. It's really pretty blatant, as the resonant frequency is many, many magnitudes greater than the other frequencies.

Part 2-

It's my understanding that you can vibrate molecules enough to break their bonds (give them kinetic energy that is greater than the strength of their bond); however, I don't think this is a method that will produce any results and if it would, an enormous amount of energy would be required to do it. If it would work (again, I'm very skeptical that it would), you would probably produce a blast loud enough to deafen yourself before you would produce one that would "shatter" water.

can you make the ornament shatter?

[XerxesNel]

With enough volume, that would be possible. I know the resonance frequency of the ornament (as you can see in the video) so I would just have to boost the amplitude. However, what you see in the video is about as much as that speaker can put out. Additionally, it's rather inconvenient to lose the ornament with which I've been experimenting hehe.

the reason i ask is if you combine your technology, and use it to resonate water(shatter it) you may be able to easily and economically produce Browns gas for cars and engines. (Browns gas is H-H-O in a monatomic state)

Part 1-

I see what you're saying. I thought you meant hydrogen is bonded to both hydrogen and oxygen, which doesn't make sense. You're talking about Klein's gas (also called Brown's gas), which some are trying to use to power cars--basically turning one type of energy into another. Electrolysis isn't the easiest of tasks and I seriously doubt sonic vibrations are going to break water bonds.

cool it resonates the glass to cause it to thrust air i am assuming. This experiment would be better if you got a with more output capabilty then that computer speaker.

[bccritters]

"break the bond" that is what i meant when i said shatter. the reason i chose to use "shatter" is because once the resonant frequency is hit(properly), ALL of the molecules will seperate almost at the same time. it will appear to the naked eye to explode in one violent episode.

My understanding is you don't really have to "shatter" water but just break the bond that water resonates at. Then it will separate.

Hey that was pretty kool. If you are musically inclined you can do the same thing by ear and don't need a scope to find the frequency. Show us more.

again, i will respond to this in private.,
