Sympathetic Tuning Forks

Watch as physics teacher Robert Douglas discusses resonate frequencies, demonstrating the sympathetic tuning forks. This set includes two C Note 256 Hz tuning forks, one fixed and one adjustable, each mounted on a wooden resonance box and a mallet. Match the frequencies to show sympathetic resonance. Move the slider to create a slight frequency difference, and demonstrate beats that the whole class can hear! See more vibrations at http://www.arborsci.com

Yes you need to have the resonance boxes to make it work. also, even though you say you have two forks of the same frequency, if they are a slightly off in the frequency pitch you will not get the sympathetic vibration. That is why one of the forks shown in the video have an adjustment to fine tune the frequency.

Good luck...

The bridge situation is much more complicated and has been debunked before.

needed help with understanding beats, thanks a lot!

I have a question , I just got 2 identical tuning forks , and when I strike one the other does not sympathetically resonate , do I need to make a resonance box to the forks specific resonance frequency in order to get sympathetic transmissions? why don't the two forks resonate~~!

please help me
