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
