Speed of Sound
    #3002171 - 08/13/04 09:31 PM (13 years, 9 days ago)

If I was travelling at the speed of sound, and passed through or was at the initial point of origin of a sound created, then outward from there I would be travelling along with that created sound, right?

Friction and other resistances aside, maybe put this scenario in a vacuum...

Would that mean that I would constantly hear that sound, since I am travelling at the same speed it is travelling from the same point of origin? It would be 1 frequency in time, constantly ringing... Does this also mean that whatever sound I make in this vacuum I hear constantly since it travels the same speed I am travelling?

you raise a good guestion..

i dont know much on the subject, but sound doesnt travel forever.. i mean.. when you say something, someone a mile away isnt gonna hear it..

so sound must slow down, fade out or whatever it does.. so i dont think you would be able to stay at the same pace or with it at all

sound = variations in atmospheric pressure,
which dissipate as lesser pressures, not slower speed.

therefore, sound can not exist in a true vacuum.

if you were traveling at the same rate as the variations in pressure,
you would not perceive any variations, therefore hear no sound.

You've got it Jinx.

By getting caught up in some wacky theory, I overlooked the simple definition of sound...

Thanks buddy

You'd never probably hear the sound. In either case, You'd never hear a constant sound.... that would require... well, a constant sound.

Could you clarify the question more?

A) The sound you were making would never leave your throat (but you still might be able to hear due to it vibrating through your throat and into your skull)

B) If you and the sound came from the same source (sonic boom maybe) you'd never hear it till you slowed.

C) Going perpendicular to a sound... I'm unsure of the exact reason, but I doubt you'd hear it either.

since ure traveling at the speed of sound in vaccum ull hear a constant buzzing sound which will be a repetition of the initiation of tht sound , like a loop, and ull keep on hearing it and it wont fade out cause ure in vaccum and theres no friction.

  being that you're in a vacuum the sound would have no medium to travel on, so there would be no sound, as proven by the movie Aliens:

Another interesting aspect of moving sound sources is the "doppler effect".

light heat and sound [Re: BufferOverflow]
    #3016443 - 08/18/04 02:10 AM (13 years, 5 days ago)

youd be in a constint sonic boom. and as jinx said in a vacum there is no sound.

what is kidn of interesting is how heat energy can go through a vacum. or is it only light that can pass through a vacum and creat heat on what it hits?

peace

Heat is molecules running around bumping into one another....so it'd have a hard time traveleing thru a vaccuum

Light, however, acts a both particle and wave, allowing it to carry its own energy thru a vaccuum.

yea i sat there and thoguth abotu it. and thats why my second sentence has the light thing. still pretty interesting though.

i love physics. its liek candy for the mind.

Evidence? Only querying this because at present i am studying physics and this is one of the phenomena scientists have yet to deliberate on. There are reasons to support it being a particle, and reasons to support it being a wave/ray. However it cannot be both.

Quantam theory, my man....

It's the duality principle....if you're asking that, you know that there are reasons to look at it both ways.

Personally, i think it's a lack of the proper symbolism/math to express it...
altho string theory is looking promising (if we could just figure it out.....)

yea its called a photon even sounds like a particle eh? so they must have deliberated, at least teh majority. haha

and if you dont belive it. then alot of physics and chemestry are down teh tube. and thre is too much evidence proving it is true then isnt.

and what is that test that shoots single photons through a opening. and when testign to see if the photons are going through the whole they go as a ray.(straight through) and when not tested they creat a interference pattern like a wave.

Quantum electrodynamics is the branch of physics that you should check into the_notorious.

Quantum mechanics really boggles my mind....here is a page talking about the wave-particle duality aspect of it, http://encyclopedia.thefreedictionary.com/Wave-particle%20duality

From this page, there is a link to the test, "double-slit experiment", that the_man mentioned. http://encyclopedia.thefreedictionary.com/double-slit%20experiment

I'm firmly convinced that the only reason why the duality aspect of a photon is unresolved (as well as many of the seeming paradoxs that abound at the quantum level) is that we have yet to find and implement the correct mathmatical dialect.

What that is, i have no real idea. But research into n-dimensional topography and n dimensional non-eucledian math is probably the best bet for it to show up in.

Just my thoughts on the subject.

I'm only convinced that I don't know enough to be convinced of anything that I know.

For those of you that like "mind candy" (I love that description, thanks the_man) Kaku's "Hyperspace" book contains an easy to digest discussion about higher dimensional space and how it allows theories like superstrings to remain consistent.

if you were going the speed of sound and spoke, you'd think the auditory sympathetic vibrations would move at the speed of sound plus the speed of sound
