Striking tuning fork 1 initiates damped oscillations in it. These oscillations weakly 'push' tuning fork 2 via the air/support. If tuning fork 2's natural frequency is close to that of tuning fork 1, the amplitude builds up (resonance). Otherwise, it quickly dies out.
Tuning fork frequency 1: 3.00 Hz*
Tuning fork frequency 2: 3.00 Hz*
Resonance strength: 0%
*Animation is intentionally slowed down — real tuning forks vibrate at hundreds of Hz (e.g., 440 Hz = note A), but the physics of resonance — frequency matching — remains the same. Bridges can resonate to footsteps, glass to a singer's voice, or cymbals to rhythmic impacts.
