Harmonic oscillation in a levitated water drop Ultrasonic standing... waves levitate a water droplet and flatten it into a disk. Modulating the sound at its resonance frequency excites harmonic shape modes creating rotating "star drops"show more

How sound waves can influence physical matter, revealing intricate... geometric forms that change with frequency and amplitude. This is a a sound wave at a frequency of 528 hertz that is travelling through water.show more

IN 1953, A WORLDWIDE AGREEMENT WAS MADE BASED ON... AN IDEA BY THE ROCKEFELLER FOUNDATION TO CHANGE THE FREQUENCY OF MUSIC. THEY CHANGED IT FROM IT'S NATURAL HARMONIC RESONANCE 432HZ TO THE CURRENT CONSCIOUSNESS SUPRESSING 440HZ.show more

A water-filled TIBETAN SINGING BOWL, when rubbed with a... leather-wrapped mallet, exhibits a lively dance of water droplets that emit a beautiful HAUNTING sound. The fluid VIBRATING inside the closed edges of the bowl create a FARADAY EFFECT, the waves produced shape-shift... AND??show more

Science 8 students are visualizing waves in Physics. Longitudinal... sound waves from Mr. Mitchell’s trumpet are being transferred into a visual standing wave at the right resonant frequency. Physics is fun!! 😃🔥 #sridge #sridgeacademics #physicsfunshow more

That’s insane! 🤯 A student built an acoustic levitation... divide with an Arduino board. He built it using an Arduino Nano, a motor driver, and 60 ultrasonic transducers that can levitate low-density objects in place indefinitely. The transducers send out 40 kHz waves that create standing waves. The interference pattern produces nulls that trap objects. High-pressure areas form below and above the object, locking it in the low-pressure area between them. The transducers produce two sound waves moving in opposing directions at the same frequency and amplitude. The effect is that the low-pressure areas don't appear to move, like whipping a rope from both ends and having the wave meet in the middle. Sound waves are oscillating at high and low pressures. By creating a sound wave that doesn't move forward (a standing wave), you create areas of constant pressure. 🔉 Objects get trapped in the null points between high-pressure zones. The craziest part is that this was made more than 7 years ago! DIY levitation 😮‍💨 Reddit link: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →show more

🚨 Sound… can create light. Not metaphorically. Literally. In... a lab, a tiny bubble in water is hit with sound waves. It collapses so violently… it flashes. This is called sonoluminescence. Energy → pressure → collapse → light. Now zoom out: If vibration can compress matter enough to produce light… what else could emerge from structured oscillation? In my framework: Light = imbalance resolving at extreme density Structure = where energy organizes itself into form So the real question is: Are we looking at a weird lab effect… or a fundamental process happening everywhere?show more

A tetrapod is a concrete block designed to prevent... erosion by dissipating wave energy along coastlines. Its tetrahedral shape allows water to flow around it, reducing the force of incoming waves This is how they are madeshow more

🧊A dramatic calving event at Alaska’s Holgate Glacier was... captured on camera, sending massive chunks of ice crashing into the water and creating a spectacular splash.show more

A water hose can be attached to a speaker... so that it vibrates at a certain frequency, say 24 Hz. You can see this effect through a 24 fps camera and if you change the vibration frequency you see a different pattern. [📹brusspup]show more

Edge-induced Faraday waves happen when you rub the rim... of a bowl making the edge vibrate, this vibrates the water at the edge and the motion spreads. When the vibration gets strong enough, the flat surface breaks into regular standing wave patternsshow more

This video looks like a rotating wheel. But watch... just one single sphere. It never rotates. Every ball only moves in a perfectly straight line back and forth. This is simple harmonic motion where linear position follows: x = R cos(ωt) By perfectly offsetting the timing of each straight path, the collective motion creates the illusion of rotation.show more

non aesthetic things This is a gravity dam It... withstands the horizontal force of water using its own weight, gravity holds it down, stopping the water in the reservoir pushing it over This one is in China and is the Xiaolangdi Dam, here the reservoir is releasing watershow more

Spotted Lake in British Columbia, Canada is a rare... mineral lake that forms colourful “spots” in summer as water evaporates. High concentrations of salts and minerals separate into circular pools, creating its unique patterned look.show more
