Resonance with Tuning Forks

Описание к видео Resonance with Tuning Forks

Two identical wooden boxes, open at one end, have identical tuning forks attached at the center of the top of the box. When the tuning fork is struck, the sound is amplified by the resonance occurring in the box. When one box is placed such that its opening is a few centimeters from the other’s opening, striking one tuning fork sets up a sympathetic vibration in the other.
