I love how your videos are made in such a way that you introduce the question, and 10 seconds later it would seem your not talking about anything related at all, but of course it is related and then you connect them. Just thought this observation was interesting
But what's the Title of the vid???? Gee It's kinda hard to _Guess_ when he starts off with a 5min *EXPLANATION* without *ANY* demonstration of the thing that *I'M* supposed to figuring out... It may still be a cool vid, but with that title... it put me off immediately because I wasn't shown something to figure out and instead am treated to a lecture about things I already understand and *STILL* haven't seen the damn thing *I CLICKED ON THIS FOR!!!*
Your own reaction to the experiments you do make them so much better than they would normally be. You're like a small child in a candy store, so filled with happiness. Good stuff.
Great explanation of harmonic frequencies. I'd always thought they were somehow magically produced along with an objects main resonant frequency every time, which has puzzled me for YEARS. Turns out they're just valleys in the frequency/energy graph (i.e. the frequencies both higher AND lower than them take more energy to produce).
Notice the pipe length is about the length of half of the aluminum rod, but about an octave lower. This is similar to a clarinet, flute comparison. A clarinet and flute are about the same length, but the clarinet is about an octave lower. The clarinet is a closed pipe and the flute an open pipe. The trumpet is a different animal though, and this experiment is much more related to a clarinet. A spectrum analysis of the pipe sound also shows stronger odd overtones similar to a clarinet sound. Great visual explanation of an audio phenomena, and a must see for my clarinet students! Thanks.
That was great! If I were a science teacher I would assign your videos to my students for extra credit! I cannot believe how much I learned in those 12 minutes!
7:50 It works because that flame heats up the mesh at the bottom. That mesh heats up air molecules causing them to rise, so when you hold the pipe directly up and down, with the mesh at the bottom of the pipe, the air molecules travel through the pipe making it resonate, and you get that trumpet like noise
I sort of want to build a rig that has like 10 heated metal rods attached to heat sinks, except all the metal rods are 1.5 semitones apart for the ultimate discordant tritone. Great eerie Halloween setup.
@The Action Lab Hey man, I measured the frequencies after, 4:35, using an app on my phone, and I got *2500 Hz, 7500 Hz,* and *12500 Hz.* But what's cool is that, whenever you rub the rod, these extra (and annoying) frequencies of *5000 Hz,* and *10000 Hz* are added in with the frequencies mentioned above. It seems like the odd numbered harmonic factors of 3, 5, etc. are there naturally, and then all harmonics are there when you rub it. Care to guess why? (I don't know myself, by the way)
Watch (or just visualize) the spring demo again. The even harmonics have a zero-point where the fundamental frequency had a peak. The odd harmonics have a peak at the same point as the fundamental. So while you can generate the even harmonics, they aren't resonant with the fundamental frequency, so the are dampened quickly.
Cmon! I mention this without the use of a phone and I don't get a heart? But I only mentioned the fundemental frquencies of the rods or the loudest frequency though. Thank you, man.
@@roberthunter5059 Interesting explanation. I need to think about that some more, but I see what you're saying. And yes, the even harmonics were the ones to dampen fastest, according to my phone app. First *10000 Hz,* then *5000 Hz,* and lastly the higher odd harmonics. The fundamental frequency, *2500 Hz,* lasted longest, which is one of the reasons the sound becomes more pleasant as it quiets down.
You guys are awesome! I love this insight! So interesting, I need to redo this video and actually talk about this. Dang Jos what app are you using to measure the frequencies?
@@TheActionLab Haha thanks man! The app I'm using is called Physics Toolbox Sensor Suite. It's amazing! It gives you a g-force meter, accelerometer, gyroscope, barometer (if your phone has a pressure sensor), sound meter, and a lot more. The function in the app that I was using is called *Spectrogram (Audio).* If gives you a sort of highlighted area of all the frequencies of sound your phone can pick up from a few tens of hertz to 16k hertz. I've even used it to identify dropped US coins (they have specific fundamental frequencies as well).
It's "obvious" why the pipe causes convective air flow, but not at all clear what is causing an oscillation. Just moving air through the tube wouldn't make it "sing" (put the tube in front of a fan or over a pot of boiling water, I'm sure it would be silent. I suspect the sound is from variation in air speed through the tube, and not the tube itself vibrating (which is why you can hold the tube anywhere.) There should be a speed of incoming air over the hot screen that results in a steady-state (no singing). But something about that system prevents it from finding an equilibrium point, and instead keeps oscillating around it at a frequency dependent on the length of the tube. Does blowing into the tube (from the screen side) while it's singing shut it up? How about moving it laterally? (Tube is vertical with a hot screen, but being moved horizontally like how you remove it from the flame.) How about if the tube was held in a ring stand while the screen was heated, and instead of rapidly moving the tube away from the torch, you gradually remove the flame?
You are right that it isn't obvious how the sound is generated. I am actually not 100% sure so that is why I didn't go into detail. However, if I had to guess I would say that when the air gets heated the volume increases greatly. The incoming air flow is low compared to the outgoing air flow. So we can consider it as a tube closed at the one end (near the mesh) and open on the other end. This is the same a trumpet which creates standing wave solutions at the ends of the tube.
Why does one actually whistle with lips? You blow air at a steady pace but still create an oscillation (sound). The reason is the creation of a "Karman street": a trail of vortexes, originating from the lips in a periodic fashion, created due to turbulence in the air. Vortexes impart momentum to your lips which in turn self-sustain the formation of the "street". These self oscillations (technically, a "limit cycle") are what ultimately produce sound. The frequency of the oscillation is related to the rate of production of vortexes (roughly speaking and very unprecisely, the slower the air flow, the lower the frequency). The same occurs in your "singing tube": turbulent motion through the graticule creates an array of vortexes which impart momentum to the grid and put it into a self-oscillatory state. Notice how as the temperature gradient decreases (and thus the number of vortexes and their rate decreases) the pitch of the tube actually bends lower. There's a lot of interesting physics going on in here which has little to do with resonance actually: the non-linear convertion of a steady linear motion into oscillation (same occurs also with that rod, or with a bow on a string, or when your door just creaks), the creation of ordered patterns in turbulent and chaotic systems, limit cycles just to name a few.
@@TheActionLab warmer air has more energy and tends to be more erratic, it's not the air persay, but rather the erratic bouncing off the wall of the pipe and other air molecules by the air itself causing the sound, which is notable for how it gets lower and less as the air temperature bottoms out again
@@Omnishredder and Fabio Cavaliere --Awesome insights! You are right that for the tube there is much more interesting physics going on than resonance. The fluid dynamics is the most interesting part!
