Using a Resonance Tube to its full potential!

[@VoidHalo]

This is great fun. I was doing similar experiments with a function generator connected to a speaker and a length of PVC pipe. I love wave physics. It applies to so many areas. Electronics, mechanics, fluid dynamics, quantum mechanics, and so much more. I could gush for hours. It was really fun watching you guys performing similar experiments. As soon as I saw the word "resonance" in the title I was hooked. I didn't care what medium, or what context. lol.

Thanks 🙏 great comment! If you love resonance you should check out our resonance system… lots of cool things to do with that too 😀 no video on it yet though I’m afraid.

where can i get the lookup table?

[@LascellsScience]

@MikeRaphson thanks for your question, Mike! You can create your look up table in MS Excel. This gives you theoretical values of the resonant frequencies you should be able to find using the equation f = nv/2L. For the first harmonic type =1*v/2L Second harmonic type =2*v/2L Third harmonic type =3*v/2L And so on. Where v = the speed of sound in air in m/s, and L is the length of the tube in m. Please let us know if any further help is needed! 🤓

Do you make a larger one?

[@LascellsScience]

Not in length, but we do a larger bore amplified unit that’s real good for the Kundt’s tube experiment.

You could technically make one as large as you want. If you've ever yelled into a tunnel to hear the echo, you used an extremely large resonance tube. Being so wide, the resonant frequency would just be quite low. At 60hz, the wavelength of sound is 5.5 meters (around 20 feet). You would also need a more powerful sound source, since you're using such a large tube, compared to the one in the video. But, you could absolutely find the resonant frequency and do the exact same experiments. In fact, you don't even need sound. You can use light in a reflective tube and get similar results because light acts like a wave. Or you could do it with waves in water. That's why I love wave physics. It can be applied to so many different things. Electromagnetic waves, sound waves, waves traveling through water, electrical waves like the sinewave coming from mains outlets. Even matter itself acts like a wave.

Great video, but it was a bit tough to watch. Your voice was much quieter than the sound of the speaker, and the tone playing gave me an instant headache! The formulas aren’t too hard to follow, but it would be super helpful to display them (and the spreadsheet) on the screen as well!

[@LascellsScience]

Thank you for that, we thought people might want to hear the resonance too. But you’re right, we could mix the audio better. Thanks again for the feedback

>sig gen Stop please. It doesn’t sound how you think it does.

Sorry can you please comment further?
