bob marely hey Bob Marely, (quite horsey) it's actually not that hard. Yes, not by far simple, but basic knowledge about soundwaves and light actually makes it very achievable. No one's insecure here, or proving their intellectually ability. Also no one's a genius, ain't my fault if the Western literacy rate goes lower than expected.
*@Bryan Rolfe, Try this:* Make a tune or similar that starts with really low hertz and continuously changes like +1 Hz per second, then you also program your strobe light to match the frequency change & start on the same Hz, and record the whole thing.
Thanks! I tried to read the "about" section in order to know more about you, what you have studied and where. But there is no information. You explained clearly the topic which I am interested in because I am studying the sound treatment of an acoustical room, I like a lot the acoustics, but, have no mathematical o physics knowledge, so, your video helped me a lot. Thanks!
That's awesome that we can learn to use frequencies to break things, we will really start to use our kowledge when we start learning how to use sound and frequencies to create things. Cheers mate :)
keeping water in the correct resonance will make hydrogen at low amps, you can also subject it with 3 frequency of its brake down and it will work well, also monitoring software to adjust for temperature would keep things consistent and lot current draw.
thanks I want to visualize sound and have worked out that at 343 m/s speed of sound in air, the lowest frequency to the highest frequency we can hear (20 Hz to 20 KHz) the wave lengths would be 20KHz 1.715cm , Middle A 440 Hz 77.9cm Middle C 256Hz 1.715m, 20 Hz 17.15cm
The wavelengths aren't indicated correctly for the standing waves. Each vibrating "loop" is marked as 1 wavelength, but it's actually only half a wavelength.
Loved you video. Please do a tutorial on how to build a strobe like yours (or share your build plans). I'm in a 3rd world country and desparate to build a stroboscope like yours. Thank you in advance.
Maybe I will someday, but right now I'm sailing around the world on a small boat, and don't have the time or resources. However, I do have an Instructable that has some instructions: www.instructables.com/id/Seeing-Sound-and-Breaking-Wine-Glasses/
If you can live with low brightness, you can use this simple solution, I found few weeks ago for myself :) : pbs.twimg.com/media/DTV8iz4XUAA13Oy.jpg. You only need the audio port and the LED. If no resistor is included in the audio port, you should use one! As frequency generator you can use an online tool like www.szynalski.com/tone-generator/
Antonio Noack Thank you so much for sharing this info. I'm definitely going to check this out and try make a plan. You've done your good deed for the day ;)
It might not be bright enough (and you've to set your music to full volume (because the default voltage is pretty low)), but besides that it kind of can strobe :) (tested it myself). For brighter light an optocoupler probably is the right thing (as simplest more-power-setup I can imagine). With modified JS-Code you could also change the width of the strobes.
I’ve been following Nicola Tesla earthquake machines...the name given to it probably isn’t the best title however. The John Hutchinson experiment came from it..Tesla knew the number code. He’d worked it out that everything has a positive and a negative sound. Positive is heat which melts and bonds while negative is the cold and breaks..Nicola Tesla tapped into the frequency of the building and nearly caused an earthquake lol 😂 great video 👍
Funny, if you look at 1:11 where the guitar is showing, you can see the frequency in the background light on the guitar. That resonating should be the basis of this video.
If you are comparing this combination with slow motion cam the my pop up question is can it also capable to capture high speed liner moving object in slow
Bryan, where can I find the code for your strobe? I'm trying a similar thing at higher frequencies, but I'm not happy with my code. I always enjoy your videos. thanks.
I’m wondering if the resonant frequency of the wine glass increases slightly as you ramp up the amplitude, due to nonlinear effects. In that case, playing a note a few Hz above the measured resonant frequency would be more optimal for causing it to break.
1:36 -> 1:48 shouldn't we be sticking with the formula wavelength = 2(string length)/# of nodes node: the peak of a wavelength ? then the first case the wavelength should be twice the string length second case would be exactly one string length as there are 2 nodes unless you are referring to something else
if you see this comment try answer these questions i have boggling my head!! 1 could this be used in a fusion reactor to alter the atoms inside to whatrver controlled state? like you say each thing has frequences. like in theory could we use a massive version of that math wrapping the collide but so concentrated and loud it changes the position of the atoms to whatever state we choose? 2. if possible do you think the craft at area 51 had one?
That maybe misleading because it is one dimensions while time and space would map out something like the double side spiral and a standing wave of ultrasound already hidden in ambient so like some type of LED and other lighting are depending on at least 2 separated frequencies to have light visible...and without knowing the hidden frequencies and field the laws of physics is hard to be accepted
naprawdę świetny film, porusza masę fajny tematów i w sposób skondensowany tłumaczy je bardzo obrazowo; tego szukałem, obowiązkowa pozycja wśród bibliografii mojego wykładu o drganiach i falach :D
Where do overtones that are different from fundamental come from? If the wavelength is divided evenly, then we should get C4 -> C5 -> C6 and so on, but we actually get C4 ->C5 -> G5 -> C6 -> E6 and so on... Where did i lost the track? AWESOME video though! sbscrbd
I think Tesla did an experiment like this, except he made the whole building he was in vibrate, he later said had he not smashed the device that was making the building vibrate with a hammer the whole building would have collapsed
3:20 "and we can change the size of the droplet, and in this way you can *effect* it's resonance". You mean affect. "Effect" is a noun. To affect is to cause an effect on something.
Neat! But if you set the strobe frequency to half the frequency of the guitar string's fundamental mode, would you see the string frozen in place, looking permanently bent?
I experimented a little trying to see the overtones, but there weren't significant enough for me to easily pick out when checking multiples of the fundamental. If I halfed the frequency, we'd see the fundamental in two places, instead of just one. It'd look like what you see at 1:35 in the video.
I believe if you set it to half the frequency you would see the same as you do when the frequency is matched. You'd be seeing the string in its "bent" position, on every second occasion its there. If the frequency is matched, you see it on every occasion. But to us, the two would look the same.
Great information and very interesting delivery. Although Im disappointed you used a picture of Bill Nye the "science" guy. He is an actor not a real scientist.
At 1:41 he talks about overtones of the fundamental and how these are always "integer multiples" of the fundamental. Hm, reminds me of the quanta in quantum physics.
Haha, hard to say. But one factor is that I'm no longer producing these types of videos, as I am currently sailing around the world on a small boat (see ruclips.net/channel/UCQnn8YwfzT8_TyJMswv6Ehga). However, I do plan to come back to producing this type of content once my voyage is over.
Hi! I want to do your strobe tuning at my home. I bought a cheap "party strobe 36 leds" on ebay (you can search and easely find them, they are very popular) - but they are not flashing short enough each 'shot'. Can you help me make the leds flash in shorter time with your knowledge of electronics or programing?
Hi Bryan, really interesting video and quite close to some experiments I've been doing with cymatics. I was wondering if you could possibly share your code for the strobe light? I'd love to visualise some of the patterns using precise frequencies and have been struggling to get precise strobe flashes. I understand if you want to keep it private but I'd much appreciate it if you don't mind?
1:36 wait wait wait. Brian - " There are higher frequency modes that we can isolate by *decreasing* string tension" ?!?!?!?! Why decreasing? Aren't you increasing the string tension ??? Please correct me if I'm wrong!!
Haha, I'm flattered. The main reason, I'm guessing, is because I'm not producing new videos at the moment. I'm currently working on a much bigger project that prevents me from making videos.
awesome video! but now I'm scared... 416.5 Hz is not that high of a frequency.... I'm kinda betting I could try and break glass with a trombone (not sure I want to find out, though)...

OMG that glass shattering was awesome, great explanation too!
Hopefully, the producer of this video ran a filter to soften the frequency from the glass vibrating and breaking! :)
The clip of you tuning the guitar by sight really ROCKED my world!…..
I was looking for a video that visualized the sound wavelength of guitar gain. Stumbled upon this and I'm in awe.
You are just genuinely a genius
No... It is extremely simple.

Hahah maybe genius is a bit too far but this is definitely NOT simple. I mean look at that phd paper. Hard, extremely hard.
