What does a Rubens tube demonstration?
The “Ruben’s Tube” demonstration shown in the video gives a dramatic and visual representation of sound waves creating standing waves in a pipe. Whether or not you light the gas, once the speaker is on, there are sound waves traveling back and forth along the tube.
How does a Rubens tube work physics?
Explanation: How it Works The compressions signify zones of high pressure and the rarefactions are low-pressure zones. Since the Ruben’s tube is closed at one end, standing waves of sound are setup inside. Hence, at places of high-pressure differences the gas escapes out with high velocity and the flames shoot up.
What is a pyro board?
Pyro Board: An Audio Visualizer Made From 2500 Individual Flames Using Simple Rubens’ Tube Physics. Invented by German physicist Heinrich Rubens in 1905, the tube uses flames to demonstrate the relationship between sound waves and sound pressure that is passing through the tube.
How does a flame tube work?
The flame tube (aka Rubens tube) is a waveform visualizer. It works because sound is a pressure wave. As sound moves through a gas like propane, the wave alternately compresses and expands the gas in different regions. Between these high-pressure points will be low pressure points that create lower flames.
How does a pyro board work?
It works because the sound pressure from the speakers causes the flow rate of gas leaving the holes to vary, which results in a visible “standing frequency” of flames, i.e. a flaming VU meter. They have a steel box with the evenly spaced holes on the top, and two speakers attached to the sides.
How many holes does the musical fire table have?
The team’s ‘Pyro Board’ is made up of 2,500 holes and is connected to a sound processor that pumps sound waves through the holed board—effectively making each flame from each of the 2,500 holes dance to the beat of the music.
