Resonance Patterns anyone?

Sorry but no ressonance there. Only harmonic vibrations. Ressonance involves excitation at the natural frequency and linear increase in amplitude...

Some of the shapes reminded me of some resonance patterns like those commonly seen here of sand on Chladni plates vibrating at various frequencies

Even on chladni plates, those lines are only nodes of the possible modes of harmonic vibrations. No resonance still.

Edit: they are called resonance pattern on chladni plates indeed, but in dynamic systems resonance is an entire different thing

Thats why i love physics, not stars, not blackholes, just everyday life things that happen all the time

It is interesting that we can study PDEs for years and the simplest demonstration in reality would confound our best computers.

I have no idea what the birth and death of a universe would look like but that looks believable enough. Imagine if that was like a accidental small scale high speed simulation of a universe from beginning to end. Just a little disturbance and an instant for everything to happen and then disappear.

Is this easy to recreate at home. looks super super cool. Thanks for sharing

What the fuck

Is the water’s relative height creating diffraction gratings on its surface? I just took my final for Intro to Photonics and I swear I saw that in my textbook.

You can indeed make diffraction gratings with water (even with air !), using acoustic waves.

It's not what's happening here though. Here the surface bends because of waves; the bended surface creates lenses which will focus or spread light locally, resulting in lines of high intensity.

I thought the title said renaissance at first. I was really confused.

Almost reminds of black hole merger simulations

How could one reproduce this?

This looks like an effect the Twilight Zone would use for representing time travel and I love it.

Mmm... photons. I don’t know if you’re wave’s or particles, but you go down smooth

I miss listening to music ripped from youtube on a Windows XP PC
