TRUMPETER PLAY FIRE IN CLASSIC PHYSICS EXPERIMENTS TO SHOW SOUND

Rarely do we manage to “see” the sound. We can sometimes notice digital ripples in voice recordings, but observing sounds, especially in real life, is a rarity. However, a classic physics experiment allows us to do just that. It's called a Rubens tube, or standing wave flame tube, and it shows the relationship between sound waves and sound pressure.
A viral post on Reddit demonstrates what this looks like in practice using a tube-operated Rubens tube. The fascinating result is a breathtaking demonstration of scientific principles.
The physical experiment was developed in 1905 by the German physicist Heinrich Rubens. The assembly is a length of pipe with holes drilled along its top and sealed at both ends. One end is a propane tank (or other flammable gas source) and the other is the sound source.
The chimney is then lit and a stagnant flame appears. When a sound is produced - in this case a trumpet is playing - the vibrational pressure of the sound waves allows the gas to escape and forms the sound curve.

The trumpet participant suggests how fast sound waves change, and the way the diverse notes in his song play a position in manipulating the flame. It’s a reminder that even the smallest matters in our global are extremely good while you prevent to recollect the physics of it all.

Scroll all the way down to see the trumpet Rubens Tube video that has long gone viral in addition to greater films proposing the experiment.
