Resonance frequency is the natural frequency at which a material, structure, molecule, or system responds most efficiently to energy input. When energy is introduced at a matching frequency, the target system can absorb and respond to that energy with greater intensity and efficiency.
In physics and engineering, resonance occurs when a waveform interacts with matter at its naturally responsive frequency. This principle is widely observed through sound science and nature — including acoustics, electronics, radio transmission, structural engineering, vibration analysis, and molecular interaction systems.
