Can Chladni Figures Be Formed on Oscillating Plates?

In summary, the conversation discusses Chladni figures formed on vibrating plates and the possibility of using oscillating plates instead. The important factor is the ratio of the plate's height to its size, which affects the waves across the surface. The size of the grains also plays a role, with larger grains potentially having a greater impact on the formation of Chladni figures.

i suppose you've heard of the famous chladni figures, formed on vibrating plates, because of resonance...
well, i just wanted to know if there have been experiments with "oscilating" instead of vibrating plates. do we receive the same waves across the surface, if, let's say we have an amplitude of 15 cm?

You can't answer that without knowing how large the actual plate is. The key point is the ratio of the height of the plate to the the size of the plate. The mathematics of the problem assumes that ratio is small.

How about the size of the grains? i suppose it matters a lot if they are not sand, but let's say balls, with a few milimeters diameter
 

1. What are Famous Chladni Figures?

Famous Chladni Figures, also known as Chladni Patterns or Chladni Plates, are complex patterns that appear on the surface of a plate when it is vibrated at certain frequencies. They were first discovered by German physicist and musician Ernst Chladni in the 18th century.

2. How are Famous Chladni Figures created?

Chladni Figures are created by placing a thin plate, such as a metal or glass plate, on a base and then bowing or vibrating the edges of the plate with a violin bow or other tool. The vibration causes the plate to resonate and the sand or other small particles on the surface to move and form intricate patterns.

3. What factors affect the appearance of Chladni Figures?

The appearance of Chladni Figures can be affected by various factors, including the shape and material of the plate, the frequency and amplitude of the vibration, and the amount and type of material placed on the plate. These factors can all influence the complexity and symmetry of the patterns formed.

4. What is the significance of Famous Chladni Figures?

Chladni Figures have been used to study the properties of vibration and sound, and have also been applied in fields such as acoustics, music, and materials science. They have also been used in art and design, and have been featured in various musical performances and installations.

5. Are there any real-world examples of Chladni Figures?

Yes, there are many real-world examples of Chladni Figures. They can be observed in vibrating plates, such as cymbals and drums, and in other natural phenomena such as sand dunes and ocean waves. Chladni Figures can also be seen in everyday objects, such as the patterns on a vibrating smartphone or tablet screen.
