# Thread: sound wave vacuum possiable?

1. i didn't know how to ask this question because
first English isn't my main language
second this line is not my line of expertise
and third i didn't know where to ask this question

but the idea is this: is it possible using sound waves to repulse oxygen
or in other words:
if i were in an environment that consists only of oxygen,was it possible using a sonic device to create a vacuum. and if it is, whats the frequency or how to calculate it.

p.s.
same with nitrogen.
and i posted same question in chemistry
because i didn't know which science is more related to this question

2.

3. physics is more related to it, physics has to do with energy and chemestry with atoms but that is an intresting idea its sort of like what they are experiminting with somewhere I don't know where with bubles what they do is they run a high frequency noise through water and a bubble filled with nothing is created since it is filled with nothing it implodes right after it is created resulting in tiny weeny explosions that produce a light that you can see with the naked eye.

Sound waves are by definition stress waves in a material. In the case of a gas they are primarily compressive waves.

But the operative condition is that they are waves in a material. A vacuum is a lack of material, so there can be no sound waves in a vacuum.

What is it that you are really trying to do ? There has got to be more to it than just this question.

5. I think he means sound waves to compress a materiel making a vacum like so sort of I think
you start with /./././././././././ when waves are passing ///../../../.././///../.../../.././/// so where the wave has decompressed the materiel there is a vacum the thing is with any gas you would only have less gas particles not a complete lack of gas particles this idea could only remotly work with liquids put then you would make a VACUM that would be low pressure to the sorrounding liquid and liquids go from high pressure to low pressure.

6. well what i meant...

air is basically particles of oxygen and nitrogen(i know i didn't include the other 1%).
i thought maybe its possible to make such a wavelength that will make a bigger distance between the oxygen and the nitrogen particles, by making them move in that cretin wavelength, or something like that.
kinda like that bridge "Tacoma Narrows Bridge" it fell apart because it entered a certain frequency, and the wave was passing through it...

or like electric circuits if you connect a coil, a capacitor and a resistor in a line and give a cretin ac wavelength and measure with an ac volt meter you can see that the sources voltage falls on the resistor and the wavelength is passing through them...

That won't work.

Voltage is not a physicsl "thing". There is no lack of "something" when the voltage is zero.
