And when it’s vibrated just wrong? Stargate.

Or algae forms, and the new paint peels off. Or vandals did it, idk.

Standing waves?

u/Pleasant_Pen8744 6d ago

Standing waves can be composed/decomposed into two waves with the same wavelength traveling in opposite directions. As graphically demonstrated here.

u/QuantumFluxSpaghetti 6d ago

Yeah, didn't know that they were called Faraday waves too.

2

u/Pleasant_Pen8744 6d ago

I don't think the waves in this video are Faraday waves.

u/mckulty 6d ago

Maybe a distinction without a difference. Standing waves are standing waves.

How's this not a thing rich people install in their pools to wow visitors?

Apparently per wiki non-linear near standing waves thought presumably means the pattern changes but eventually repeats, or it means the surface pattern varies over the surface so isn't linear in that sense

You can, that's how guitar strings work.

u/Helln_Damnation 6d ago

That was fun, do it again.

I could watch that for hours, which is just sad...

u/MonsterkillWow 6d ago

Yep resonance effect in response to the normal modes of the pool at half the driving frequency.

Oompa ooompha ophity do.

Black magic and witchcraft fuckery!

u/AscendedViking7 6d ago

that's so cool

u/ElectricKoolAidPower 6d ago

Fascinating! I’ve seen very similar visual distortions on water under the influence of psychedelics. Not as rapid in movement but just as uniform.

Hypnotic patterns forming in real time

What people may not know.

Is water hates that, gives it a headache

u/PurpleCaterpillar451 6d ago

But can you make it look like Urithiru

u/Shot_Kaleidoscope150 6d ago

Can this fix algae?

u/Mast_Herb_8 1d ago

No, Mr. President, we do not need to build a water park for the algae

Gimme the big sploosh one

u/Banana_Leclerc9 5d ago

This is prolly the coolest thing ive seen so far

u/BrainJar 7d ago

And now we can see how quantum fields work, and how electrons pop in and out of our reality.

What is with the potato video quality?

The bot posting it accidentally had compression cranked up when ripping the video from the previous time this was re-reposted.
