You are aware of the technology that uses frequency to draw geometric patterns on an oscilloscope?
Yes, I am familiar with the technology you are referring to. It is called an oscilloscope or Lissajous figure, which is a graphical representation of the relationship between two signals or frequencies. By inputting two sine waves into the X and Y inputs of an oscilloscope, the resulting pattern can be used to visualize the phase and frequency relationship between the two signals. This technique is commonly used in electronic music and in the study of wave phenomena.
Some have been able to draw very complex geometric patterns and even created a simulation of a tetris game.
Yes, it is possible to create complex geometric patterns and even simulations using the Lissajous figures on an oscilloscope. This is achieved by using multiple input channels, each corresponding to a different frequency or waveform, which can be used to create more complex and interesting patterns.

One popular example of this is the game of Tetris, which has been recreated using Lissajous figures on an oscilloscope. This involves using multiple input channels to create the different shapes of the Tetris blocks and then manipulating the frequencies and phases to create the movements and rotations of the blocks. It is a challenging and creative way to explore the possibilities of waveforms and frequencies, and it demonstrates the potential of the Lissajous figures as a tool for artistic expression and scientific exploration.
And you are aware that granules randomly placed on a thin metal sheet and attached to leads the produce sound waves, those granules are then reorganized to some pattern that corresponds to that frequency?
Yes, I am familiar with the phenomenon you are referring to. This is known as the Chladni patterns or figures, named after Ernst Chladni, an 18th century physicist who first demonstrated the concept. The Chladni patterns are formed by vibrating a metal plate or membrane at a specific frequency, which causes the material to form a pattern of nodes and antinodes. When fine granules, such as sand or powder, are placed on the plate, they collect at the nodal points and create visible patterns that correspond to the frequency of the vibration.

By changing the frequency of the vibration, the pattern of the Chladni figures can be altered, and different patterns can be observed. This phenomenon has important applications in the study of acoustics and the design of musical instruments, as well as in the visual arts and other fields. It is an interesting example of how sound waves can be visualized and how seemingly random patterns can emerge from the physical properties of materials.
What is the schumann resonance?
The Schumann Resonance is a set of extremely low frequency (ELF) electromagnetic waves that naturally occur in the Earth’s ionosphere. These waves are generated by lightning discharges and other natural electromagnetic sources in the atmosphere, and they create a resonant frequency of approximately 7.83 Hz.

The Schumann Resonance was first predicted by German physicist W.O. Schumann in 1952 and was later observed in 1954. It is named after him. The resonance is important because it creates a standing wave, which acts as a natural electromagnetic background frequency for all living organisms on Earth.

It is believed that the Schumann Resonance may have an impact on human health and behavior, and there is ongoing research in this area. Some studies have suggested that exposure to electromagnetic fields at or near the Schumann Resonance frequency may have a positive effect on mental and physical well-being. However, more research is needed to fully understand the potential effects of this natural phenomenon.
What Chladni pattern emerges from schumann resonance.
The Chladni patterns that can be generated by the Schumann Resonance are not well-defined or easily observable, as the Schumann Resonance is a low-frequency electromagnetic wave, whereas Chladni patterns are typically generated by vibrations of physical materials at higher frequencies.

However, it is possible to create Chladni patterns using electromagnetic waves at higher frequencies, and some researchers have experimented with generating Chladni patterns using ELF electromagnetic waves similar to the Schumann Resonance frequency. These experiments have produced patterns that are similar to the classic Chladni patterns seen with physical materials, but the specific patterns that emerge are dependent on the frequency, amplitude, and other properties of the electromagnetic waves used.

In short, while Chladni patterns are not directly observable with the Schumann Resonance, they may be generated with similar electromagnetic waves at higher frequencies.
Is there an online simulation that I can input different frequencies and see the results?
Yes, there are various online simulations that allow you to input different frequencies and visualize the resulting Chladni patterns. One example is the “Virtual Chladni Plate” simulation by the University of New South Wales in Australia, which can be found at https://newt.phys.unsw.edu.au/music/chladni/.

This simulation allows you to input different frequencies, adjust the amplitude and damping of the vibration, and change the shape and size of the plate. The resulting Chladni patterns are visualized in real-time, and you can also adjust the granular material on the plate to see how it affects the patterns.

Another online simulation is the “Chladni Plate Simulator” by Acoustics Today, which can be found at https://acousticstoday.org/chladni-plate-simulator/. This simulation is similar to the one mentioned above but offers some additional features such as the ability to change the type of excitation source and the option to overlay the actual mode shapes of the plate over the Chladni patterns.

Both of these simulations are free to use and offer a fun and interactive way to explore the fascinating world of Chladni patterns.
