[Double Post]If you think that it does work, leave a quick comment attesting so, please. Also, the video is somewhat interesting in of itself, so even if you don't want to help me out, you might get some entertainment from it. Thanks.

Pressure = Force/Area so if you know the force, and you can measure the area, to quote john madden, "BOOM" you know the pressure. Assuming that the tank is open at the top so that it is at atmospheric pressure, then the force is just due to the mass of water. \frac{9.8 m/s * m...

no. All of these things are contrived. I don't think that the question is about applying some sort of measurement to it but rather something more abstract. Let me try and phrase it this way: The speed of light is not infinite. It does in fact have a finite speed. That being said, it can only...

@Danger: Sorry, The frequency would also be scaled up to force the nodes together

Pressure = Force/Area so yes, if the force remains the same, decreasing the diameter and thus the area will increase the pressure.

First watch the video clip below of salt being positioned on a vibrating substrate... http://www.youtube.com/watch?v=s9GBf8y0lY0" ...Then tell me why you think that this wouldn't work if I shrunk everything down so that the particles being used were ~10nm diameter and the spacings were ~100nm...

I think the question is why is it that the universe chose 3E8 m/s seemingly arbitrarily as the speed limit of the universe as apposed to so 4E8 or something even larger (or presumably smaller). So what makes that speed more special than another? I don't think that there can be an answer to...

Yes, but I am interested in simple 2-d shapes. I imagined that these equations exist as a standard set for basic shapes but it may not be the case. Possibly of interest is this video: http://www.coolestone.com/media/124/Seeing_Sound_Waves_-_Awesome/" which illustrates what I would like to...

I am primarily thinking about silicon wafers (which are only 500 microns thick and crystalline silicon is brittle). Also, do you know where I would find the equations for resonant frequencies of shapes?

I am wondering what property of a material would be of interest (or better yet if you knew some formulas that describe this property) if I want to know what frequencies different materials could handle. I am thinking along the lines of "the fat lady singing" and reaching that high note that...

do you have any idea of what frequencies could be achieved though? I am less interested in how it is done, just what can be done, or is anticipated being able to be done.

I am wondering what the upper limit for frequency is currently as far as audio signal generators go. Basically I want to know how high of a frequency I can get on a compression wave. I don't mean the theoretical limit based on the atomic spacing in the medium, but rather if I want to buy a...
