Natural frequency is the frequency at which a system naturally vibrates when disturbed from its equilibrium position. Excitation frequency is the frequency at which an external force is applied to a system. Resonance frequency is the frequency at which the amplitude of the system's response is maximized when subjected to an external force at or near its natural frequency. In summary, natural frequency is inherent to the system, excitation frequency is the frequency of the external force, and resonance frequency is the frequency at which the system's response is maximized. **
