hi,

from the latter 2 shots, it seems to me you are using a sub-woofer for making the oil vibrate, right?

and you do so with a simple/flat/monotonic sine-wave at 60Hz, right?

also, the camera is a regular camera, not an high speed camera, right?

did you ever tried using those cameras to make videos at very high frame-rates, like this?

and now to the real questions…

what’s the role of the frequency parameter in your equations?

I mean: what “should happen” if you vary/modulate that value?

in other terms…

did you ever try sending the sub-woofer&oil some different signal, say something “harmonic” – I mean a “nice” (non dissonant) superposition of waves, like this A1@55Hz from my bass?

and, similarly, did you ever tried chords and chords progressions?

I’m not sure if your model/equations can work with that, but the sub-woofer and oil complex should…

cheers

corrado

My camera is a Gopro , up to 480 fps …which is barely enough for watching the vertical dynamics of the droplet… but it is not the most intersting part, since I mostly strobe the movie at the same frequency as the excitation.

The pure frequency selects a certain Faraday Wavelength, and also determines the Faraday Thresold.

It is difficult to mix frequencies, since the Fraday Thresold is different for each excitation frequency.

Check in the youtube or facebook feed and you’ll see some musical input…and also white noise input …

for the camera: what about this “virtual” (parallelized?) high-FPS one?

https://www.youtube.com/watch?v=qRV1em–gaM&nohtml5=False

for the frequencies: I’ve studied some linear continuum mechanics (EMF), but I’m new to Faraday’s waves and pretty much scared about the non-linearity (I’m not so good at math & I did math for engineers)

PS: what about adding some “colored marker” to the oil, maybe of different weight, in order to get something like the image in the page on Faraday’s waves?

in my pdf, goto page 20 at:

Incidentally, it’s Continuum Mechanics, reallyhttp://www.servicemix.eu/_PHYSICS/2016-03-07%20-%20Ver1.0.0-rc2%20-%20Monkey%20Metrics%20-%20Semantically%20Refactored%20Special%20Relativity.pdf#page=20&zoom=auto,56.7,797.5

on the “music”:

should bring inspiration, check the word

to me, it do brings inspiration, and fun:

A Capella Science – Bohemian Gravity!

A Capella Science – Defining Gravity

cheers!

Cute 🙂 🙂 🙂
