Circular Centered Chladni Plate.mov

Circular Centered Chladni Plate. The driver speaker is attached at the center. Standing wave patterns form at particular frequencies. The sand settles along nodal lines.

[@smashshoot1389]

I am not physicist but... Anyway, this is my analysis: The vibration generates mechanical waves. These waves travel from the center of the plate to the edges. When the waves reach the edge, part of this energy leaves the plate and part returns to the center. The waves that return to the center cancel with the new waves that are going out of the center. In these points where the mechanical waves cancel each other, there are no vibrations, thus the salt stops jumping and accumulates there forming the circles.

[@jackcau1845]

hi, i am a graduate physics student, i think you are right.

[@Rapbando]

Number of circles is inversely proportional to wave lenght, and the circles offset distance is wavelenght

[@GoldSabre]

This is really cool! Thanks for sharing!

[@Wtf-rq2dg]

The lines you got are nodelines-lines of nodes,which are arranged in the case of the shape of the Chladni plate (if the shape of the plate is not complex though),but if the shape is complex,then the arranging of the nodes is not following the shape of the Chladni plate.

[@hedflux]

its amazing how the patterns seem to remain stable over a wide band of frequencies. How do the resonant frequencies related to the plate radius?

[@ianwhorton]

me hace pensar en que los fenómenos físicos como este y la gravedad que acompaña a todo cuerpo celeste, así como las fricciones entre ellos es lo que da forma esencial a nuestro cosmos.

[@CorModo]

So, the pictures do reflect the geometry of the plate.

[@BooglestationTermoil]

Cool very different results to a square plate.. what happens on a triangular plate ? Hexagon ?

[@theflexintexan2152]

Look at the grains find their way to the circles. Crazy paths remind me of Brownian Motion

[@theflexintexan2152]

How do you find out the radii of the circles before doing the experiment?

[@KuraSourTakanHour]

This is interesting but I had to turn my volume far down for listening to the higher frequency

[@cabeloDoPardal2]

the waves create lines of disturbance, whose thickness depends on the frequency: the higher, the thinner. The particles just escape from those streams of high amplitude of ressonance because they get the energy though at different times, depending on the wavelength, to adhere at thinner layers of spaces between the transitions of the waves.

[@Dazzwidd]

There seems to be a lot of people convinced that they know what's going on, but only some actually do. It is simple. The audio frequency is propagating outward from the center of the plate. The plate is physically small in terms of the frequencies actual wavelength, but still has a natural resonance. Waves going out toward the edge get reflected on reaching the edge and travel back to the center only to be reflected again. These waves either constructively or deconstructively combine with waves coming from the AF source creating standing waves on the plate. I would assume that the grains would congregate at the pressure zones between the oncoming and reflecting waves

[@infinitr7021]

Dazzwidd rings occur on wave nodes. Same as the steady points if you move a slinky up and down, but in 360 degrees.

[@mas_yaris]

so it's also make a different pattern when using different plates

[@TheAngelica2121]

es decir que las órbitas planetarias trabajan en una frecuencia de sonido?

[@honorioandrestorresortega182]

and is called the device that generates the frequencies in the video

[@BinAlladin]

You should try to put quartz crystal close to speaker and your whole body will start to vibrate !

[@plbuster]

feel like I'm taking a hearing test.....

[@RenegadeTwo]

It's probably based on the natural resonance of the plate itself. I'd go as far to guess that the wavelength of these frequencies can be derived by λ = r/n ; r being the radius of the plate and n being any whole number integer. It's been a few years since math class, so feel free to correct me...

[@MrForestExplorer]

Needs more salt...

[@sir_john_hammond]

Needs more cowbell.

[@juanosorio746]

It's just not saly enough :v

[@samirhalloumsh]

What type of plate are you using and how thick is it?

[@sangmadewira4726]

Isn't it funny how it looks like a solar system's orbits?

[@omniscient159]

So sounds ~ magnetism

[@rixille]

I have seen squares and circle plates being used; what about other geometric shapes?

[@gabrielseth2666]

+rixille I wondered the same thing. I would like to see a pentagon. I'm curious if the geometry which emerges would follow the pentagonal form...

[@christopherszerenos]

Reminds me of the Bode's Law in astronomy, when the radiuses of orbits of planets around stars follow power law scaling & take only discrete well defined values, unless disturbed by something like a collision.. this is visible in our system, in Jovian moons system and in other star systems.. some celestial resonance to produce a stable orbit?

[@brianbutcher7409]

Thus the mystery surrounding the forces of gravity and the natural order of the universe explained. In order to understand the Universe we must think in terms of vibration and frequency.

[@nathans6486]

what where to happen if you where to force a node by pinching the side? or pinching the side at 2 or more ifrant points?

[@andrewgrady7447]

I would like to know why the circular version only makes concentric circles, where as the square one makes designs.. what about a triangular one?

[@danielbarahona784]

The nodes of stacionary wave depends in the frecuency and the length, so when you have a circular shape, the length between the centar and any extreme is the same, making always the same nodes at the same distance, in a rectangular this is not the case, making a diferentes amount of nodes in diferent places due to the diference in distance, creating those diferent patterns. but its just a guess

[@philwright8280]

Good question and one I was wondering myself....same with an eliptical plate. On reflection (a pun if you think about it!) the vibrations are being propogated from the centre of the sheet and travel outwards. Everything has resonant frequencies and in this case circular lines of sand form at certain distances from the centre, depending upon those frequencies. (Renegade 2 touches on it below). With a non-circular sheet, different points on the sheet will resonate at different frequencies depending on constructive or destructive interference of the waves so the sand will form different patterns. That's my thought.... Best I get down to the DT department and obtain some sheet metal and find out for myself!

[@dharam108]

please, what tone generator are you using?

[@DIEHEXEN]

Hello SBCC. What equipment do i need to buy to try this at home?

[@gordonshumway6128]

Is the 'life' frequency always heightening? can it be augmented?

[@jmpt19]

Can i ask, whats the material of the plate?

[@ashutoshbhakuni303]

HI. Can you tell what is the plate thickness? With a bow, what thickness can be used..1mm, 2mm, 3mm or more? Thanks!

[@elono9464]

please repeat this experiment and put a scale (meter or inch) through the center, tell us about the "dancing" material (what is it salt or sugar, weight, +/- size). the question is on which frequency materials such orbits and how big the orbits are (maybe on a standard frequency). This will maybe give us a hint on some thing Thanks any way it looks nice ;)

[@jakestablettableto9453]

Whats the ,machine used to generate the frequency?

[@noreaction1]

I would like to see a meterstick showing centimeters between nodes

[@bbewmada]

It appears to add 1 ring per octave

[@engjds]

though atomic orbits are elliptic, the same kind of fundamental resonance must be occurring with the atomic forces in place of gravity, this is closet approximation to wavefunctions I have seen, wouldn't it be good if we could produce these resonances in 3d.

[@heathermcduffee7058]

What is the plate made from here?

[@JoshSitar]

This MUST be tried with a hexagonal plate. The hexagon is the most beautiful and sacred of all shapes.

[@MagicBlubber]

All shapes related to platonic solids should be attempted imo

[@Dariusz7]

tak samo pod wpływem częstotliwości solfeggio układają się molekuły w naszych ciałach . nie prawdopodobne lecz prawdziwe ! just under Solfeggio frequencies are arranged molecules in our bodies. but likely not true!

[@Clomwellschimdt]

this is a flat disc, just like the earth, which vibrates in resonance with all of creation. That is why all of the continents are perfect circles.

[@tln6576]

there was no sound audible (you couldn't hear the frequency rising) and the person didn't turn up the dial high enough

[@plumber1337]

Has anyone tried this with a spherical segment?

[@mykedoes4099]

why does the square plate make all the other shapes and the circular plate is only circles

[@bourbonfan1]

maybe? your last one right?

[@Q.Mechanic]

WooW

[@a.t1701]

this explains the shape of the orbits

[@derekxiaoEvanescentBliss]

incorrect whatsoever lmao

[@sheriffrust]

+derek xiao how?

[@derekxiaoEvanescentBliss]

What do resonant frequencies have to do with orbits. Orbits aren't even circular in the first place (even if some of the ones in our solar system are pretty close)

[@Mau5Trapp5]

Considering the recent discovery of gravitational waves, this makes perfect sense.

[@derekxiaoEvanescentBliss]

+Mau5Trapp5 as I've pointed out, very few orbits even look circular, none are perfectly so. What do gravitational waves have to do with orbits..? Gravitational waves have nothing to do with how most planets move around stars...

[@Dgannt]

This is how planets in solar systems are arranged and organized over time. And it can happen and also change (with planets both being rejected and caught) over and over, with changes happening in a very short time span. And NOT by gravity, during billions of years and static, according to the standard model which the mainstream scientists now are beginning to realize and accept.

[@gabrielseth2666]

+Fast Er what is the source of the frequency? is it the sun?

[@spencerszabados7244]

+Gabriel Seth ya I'm fairly sure our planets are orientate/arranged by gravity and forces of attraction, not cosmic sun frequency. also isn't a chladni plate just used to render a frequency's acoustics/reverberation "patterns" in a physical media.

[@xDJokerxx]

+carpo719 Would you care to elaborate on that last part? Are you referring to, for example, how electromagnetic waves move electrons?

[@AlexKB01]

+carpo719 light isn't invisible. First off, we perceive pure light as white, it doesn't need to be reflected off anything for that to be the case. When it is reflected certain frequencies are absorbed according to objects chemical composition (see 'line spectra'), giving the object it's colour. But as I'm sure you're well aware, light is simply a band of frequencies our brains have evolved to interpret and essentially 'decode', nothing more to us, birds can even see a different set of spectra to us, it's relative. It has no mass, that's why it moves at 'c', because it doesn't interact with the higgs field, so it cannot organise matter. I study physics, and this whole frequency thing is almost like a religion; little cherry picked pockets of information stretched to create an elaborate scientific theory that is so unfounded it requires something like faith to accept.

[@plumber1337]

That has been said over 2000 years ago... But we are only understanding it now... Lets just hope and "pray" that science catches up faster than the current pace of discovery.

Great Job!!!! For better understanding, of this phenomena, could you please provide more plate data such as outer & inner diameter, thickness and material properties (Young modulus, Poisson ratio)? It could be great complement to your experimrnt. Thanks a lot!!

[@carminederrico6639]

He schould also measure the distance between lines for each frequency

[@jasonsjoinery]

[@surfinmuso37]

The shape of the plate determines the shape the salt will take.

[@elrojoJazz]

galaxy frequency... would explain saturn's rings

[@Phoenixspacecraft]

Not a "galaxy frequency", but the ressonance between Saturn's and its moon's gravity. Many Saturn's moons orbit too close to the rings system to create patterns in it.

[@elrojoJazz]

Gabriel Falcão A "resonance" is a vibration! A frequency is a tuned vibration. you are just saying the same thing as me only in laymen's terms.

[@mrkiky]

Rion De Rochestia "A "resonance" is a vibration!" - Wrong. "A frequency is a tuned vibration." - Wrong. Saturn's rings are caused by phenomena different from resonance, but you have no idea what those words mean.

It does not... You do know there aren't any actual circles, right? In fact, the planets don't even have circular orbits, but eliptical ones. And they're not evenly spaced, and are really, really far apart in human terms.

[@gordonshumway6128]

[@PacoOtis]

You didn't have any professional advice as to how to present this, did you? This, likely, could have been interesting. Best of luck!

[@falubii9712]

Why are so many complete quacks drawn to this video?

[@ripplecutbuddha]

anyone doing these experiments ever think of putting sides and a clear lid on the plate so you don't have to keep adding more salt??

[@bourbonfan1]

ripplecutbuddha it would alter it

[@robbader3]

ripplecutbuddha I thought the same thing, but then I realized that there are exponentially more lines and detail at the higher frequencies, which require more in order to maintain it's consistency

[@Kylesmith-qc1bx]

wouldn't work, the salt/sand/whatever they are using is settling into the places that is does due to the curvature in the plate itself, not due to the sound waves or anything, so if you had a lid then the plate wouldn't be able to flex because it will be connected to the lid
