a great demonstration. back in the late 1980's i was given a car owned by 2 older siblings, there was a cassette radio fitted in a box suspended below the dashboard. the wood box and radio would hit a resonance frequency at about 70kph, and chew the cassette tape. the entire box would swing wildly side to side at just the right forward speed.just below or just above that speed and the tape player would run fine. i had a lot of fun destroying (and splicing) tapes demonstrating the phenomenon.
Had a similar phenomenon with my car. With the tires out of balance there was a node at 80mph and my whole front end shook. 70mph - no vibrations. 90mph - smoothe as glass. Unfortunately, 80mph is my go to

Great video ruined by background music and slow motion at the moment of truth.... (the breaking of the glass could have been repeated after in slow motion)
I used to "play glasses" as a kid. The way it works is that you slide your finger around the top edge of the glass, alternating the velocity of the movement and the pressure applied changes the frequency of sound produced. Having different volumes of liquid inside the glass produces a different sound. I managed to break a couple of glasses accidentally by hitting the natural frequency. Not dangerous but it sure was exciting!
A 1700s physician named Anton Mesmer ("mesmerize") helped make the _glass harmonica_ popular, along with Benjamin Franklin (yeah, that B. Franklin) who was a member of the Royal Academy of Sciences. The "Glass Harmonica" used that very principle of resonating glasses to produce music.
If everything has a destructive resonance frequency, does that include bacterias and infections also? If so, is it possible to eliminate diseases just by matching their destructive resonance frequency?
I remember doing something with equations that looked like the ones on the blackboard. Happily brain dumped all the vibrations and control stuff I learned.
I watched this video in the early days of youtube, but i couldn't leave a comment, because my screen shattered for some reason. Now i finally found out why that happened. True story.
it would have been better if you measured lengths of the glass and converted the wavelength to frequency. Then see if that calculated frequency matches the one that caused it to break.
Great you do with simple speaker for this experiment. Why do you increase volume just increase pitch. Can you do it without increasing volume? What is the final frequency when the glass broke?
The vibration is becoming visible, because of the increased amplitude (volume) of the sound generated by the speaker. The glass is vibrating before that, but not visibly. If you put your finger on the glass you could have felt it, though.

That was good until the music started. Not a good idea, when it's a demonstration involving sound! A fireworks display next, when you're showing how to use lasers?
@@happyforever7688 the quran didn't said : the sound can break the glass ,but said : the sound can kill the people ,for me is the same (quran 11:67 , 36:29 ) the judgment day will be a sound too , therefore that sound will destroy everything 36 :49, we know : that sound will destroy all earth ,is called : kiyamah day , did you read the 101-the surah of quran ,that sound will destroy everything( including glasses and metals ...)

Thanks bro for the advise. i'll make things better next time
@@ThePhysicsMathsWizard The video is great! Thanks for sharing :)
But the background music really distracts a bit
Did you add the background music as a safety mechanism?
@@hexistenz not really
Bollocks

Superb ... more fun to watch the glass at the end before it breaks in slow motion ...

I think there's a similar technology already where they use resonance to disinfect surfaces, but its not yet so efficient.
You have a good idea!
People have been known to damage phones and other things during this test. That's probably why they had the added sounds.
The music was not necessary. The demonstration would of been far better with just the frequency GENERATOR alone.
How to break a glass ?
Normal way: drop it (or give it to Linus, same result)
Scientific way:
I remember doing something with equations that looked like the ones on the blackboard. Happily brain dumped all the vibrations and control stuff I learned.
Why did you use that geh music in background music and slo mo ?
The music in the background couldn't have been more obnoxious and trite but I appreciate the upload!

"some of you many not survive"
Was good
Nice video, It's really interesting phenomena, and I remember that Tesla almost destroyed a building with your ocilator with the same situation, hahah
Looks like the glass had its own bodyguard to stand watch over it. Didn't work though, it still smashed.
Who was the genius that put background music to a video about an experiment with sound?
Great you do with simple speaker for this experiment. Why do you increase volume just increase pitch. Can you do it without increasing volume? What is the final frequency when the glass broke?
legend has it that 53,401 people watching this video had their screens broken due to not wearing headphones
7J Loved this video, Mostly Shahid.
Is it necessary to continue applying the force for the resonance to continue?
I missed this teacher in my curriculum passed on
Brilliant.
So....are the fog horns trying to smash the ships???
nice video, cool prof, but showing the relevant scene (only) in slow motion is destroying the whole effect...
Very cool….he is a fun professor.
When the sound of metallica is played, plates get shattered, mainly due to angry wives.
I could not finish the video..
But why the complete glass did not break
RIP headphone users I guess.
Also SlowMo Guys recently did a video on this, so that's also worth a watch
It just broke after being told it was going to be put on hold again
Great
without glass cup can you make it that ??? because ,,,,
Everyones phone screen just shatters
No both
Need
Why does the glass wiggle before breaking ? What is the cause ?
The vibration is becoming visible, because of the increased amplitude (volume) of the sound generated by the speaker. The glass is vibrating before that, but not visibly. If you put your finger on the glass you could have felt it, though.
@@matthewwallace9280 oh ma gawd, the frewuency of the sound even at 648 hz just destroyed my ears.
Cool stuff. But there’s NO need for that absolutely stupid music. It distracts from the experiment and erodes your integrity.
Ok, next time better

Putting out better sound than Lady Gaga or Gucci Gang

Why one stupid fellow moving behind, disturbing
Damn … my phone screen cracked 😭
This means ur phone had the same natural frequency as this glass, therefore it resonated and cracked.
unduh
I see the dynamical equations on blackboard and my PTSD rushes in. The worst exam ever.
Just put your fingers on your ears

That is mentioned in quran 1400 years ago
In which part?🙏🏽

no need to wear goggles and ear plugs tbh. just a waste of money and time.
It worked !
