If the second box shares that same natural frequency, those waves hit it at just the right moments. Each wave adds energy at the perfect time, causing the vibrations to build until the second box shakes powerfully—without any direct contact. However, if the second box is tuned to 512 Hz instead, the timing is off. The waves arrive out of sync, the pushes don’t line up, and the en
