Tuning Fork Resonance A-level Physics - AQA A Level Physics

A really simple idea which shows how a tuning fork can pass its frequency to another tuning fork through a sound wave.
The first wave is of the correct frequency 440Hz and passes to the 2nd unless you alter the mass on the tuning fork which changes it resonant frequency.

Clever use of the ping pong ball to illustrate clearly the sympathetic resonating tuning fork (the human eye cannot see a tuning fork vibrating at 440Hz or 440 times a second)

[@NRFNRR]

Eye can.

[@mr.trashbin307]

this is similar to playing one cello and the strings of another cello in the same room vibrate.

[@youTubeify]

And in an orchestra, even if all the violins (or cellos) are playing exactly the same piece of music what you are hearing is a complex interaction of resonances between the violins themselves and between the violins and other instruments not simply an increase in volume. Each violin will have its own unique resonance characteristic due to the violins construction and becomes, if ever so slightly, out of phase with the other violinists as the piece progresses. Yes, there is an initial tuning led by the lead violinist (concertmaster) where the resonance beat frequency is used to attempt an exact tune. Even with just two violins the resulting sound becomes extraordinarily complex kzbin.info/www/bejne/pZjMealuiLZpkLc

Such a clear illustration! Thank you.

[@animatedsci]

You're very welcome!

Thank you very much for the address. I placed an order and goods arrived today.(02/12/22)Excellent service.

One of the best videos on the internet

The first 2 have to do with frequency, 1 is acoustic oscillation (some fun houses/haunted houses with candles will use this to make the candles flicker)(1 could also be particularly air pressure) and 2 was resonate frequency (trick would work a bit differently or not at all if the second fork was calibrated to a different note range) .... I thought the third was invisible ink

Amazing❤

Make a thermo acoustic refrigerator tuning fork the keeps the sound wave nodes compressing in a heat synch resonance chamber

[@RlsIII-uz1kl]

I read that frequency's can effect magnetic fields. So what would happen if there's two sets of magnetic tuning forks of the same frequencys that also have magnetic fields that cause a unique magnetic Field that has some kind of application, when one stimulates the other?. Or could two pairs with different frequency that are magnetic, allow one to stimulate the other when it normally wouldn't but because of the interacting magnetfield it does? Hope that made sense.

[@animatedsci]

No idea❤️😀🤔

[@Smackyabitchupshitlips]

Could someone set up 26 of them with each frequency connected to an individual letter of the alphabet and then spell out words by hitting different forks?

[@saulgoodman8407]

What happens if you add hundreds of receiving forks? Mechanical tesla coils.. You can have as many receivers picking up that original knock

[@tristan4628]

This is how tesla wanted to make free wireless energy for the world.

[@Nkanyiso94]

What will happen if I hit 1 fork in front of other 20 forks (provided that they all vibrate at the same frequency). Are they all going to vibrate?

[@animatedsci]

Yes but the box helps amplify the signal

[@Nkanyiso94]

@@animatedsci Okay if 1 fork can vibrate 20 forks, isn't that violates the Law of Conservation of Energy. 20 forks provide a high output energy which is far greater than that of a single fork. Where is the other energy coming from?

[@animatedsci]

They do vibrate but with lower A

[@TheLionshub]

Where can I buy these forks?

[@animatedsci]

Philip Harris I think has them.

[@joshuapeterson2084]

Can you induce a resonance on a 440 tuning fork with a 880 transmitter tuning fork? I have a hypothesis that you can, but at half the efficiency of a 440 transmitter fork.

[@animatedsci]

In theory you might get something, next time I get the kit out I will have a try 😃

[@mononcyoyo]

@@animatedsci Yes I would like to see the 1st harmonic resonance if you can

[@Enterprisers0045]

how to measure the intensity

[@animatedsci]

Sound meter?

[@peterfarley]

Please advise where I could buy the exact forks and equipment being used in this experiment.

[@emmettpalaima9526]

Why doesn't vibrating a box with a matched sine wave from a transducer cause the tuning fork to move?

[@animatedsci]

It has to be the same mass

[@emmettpalaima9526]

@@animatedsci What has to be the same mass?

[@animatedsci]

The two tuning forks must be the same mass to oscillate at the same freq.

[@emmettpalaima9526]

@@animatedsci Ah, I'm not using two tuning forks. I'm doing an experiment where I use one box and vibrate it with a surface mount transducer playing a sine wave matched to the frequency of the fork. It's the same principle in theory but not working for me so I'm wondering what could be potential sources of error

[@animatedsci]

I would have thought that it might not have enough physical energy to create the amplitude required. Difficult to tell really.

[@sydneyhunt6681]

Am thinking maybe make a moter seems to be maybe a way to make a better moter generator

[@animatedsci]

???

[@ariumboroseno]

Does it work with 512 hz ?

[@animatedsci]

Maybe!❤️

[@animatedsci]

Both have to be the same!

[@ariumboroseno]

@@animatedsci its same, 512 hz, but it didn't work like that

[@animatedsci]

When the Freq are the same you get resonance

[@sirjohnahayfalcon]

Why wont energy transfer at different frequencies? How many 440 forks will resonate from one fork?

[@animatedsci]

Each fork has it's own frequency of resonance. Depends on length and mass. Hence my movable mass

[@mahadevaramachandra4273]

Where i buy this meterials

[@animatedsci]

I think it's sold by Philip Harris.
