Best Demonstration of Resonance -MIT professor demonstrates how glass breaks due to forced resonance 

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

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.

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!

A man had that idea in the early 1920s and he proved that it worked. Killing bacteria and diseases with a small cost of electricity, no drugs and no pain in NOT what the AMA and its worldwide friends are interested in. This man I’m talking about was Royal Raymond Rife. Don’t be fooled by todays scammers using Rife’s name to sell machines and dreams. Rife was the real deal and if you research into his life, work and the evidence surrounding everything and everyone around him l you will be blown away. However, be careful because once you know for a fact that the suppression of cancer cures has been going on for 100 years you may not look at the world and humanity the same. At least I didn’t.

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

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.

This means ur phone had the same natural frequency as this glass, therefore it resonated and cracked.

In which part?🙏🏽

@@happyforever7688 what is your religion ?

@@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 ...)

Ok, next time better
