Definition of resonant frequency. : a frequency capable of exciting a resonance maximum in a given body or system.
Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies, or resonance frequencies.At resonant frequencies, small periodic driving forces have the ability to produce large amplitude oscillations. This is because the system stores vibrational energy.he intensity is defined as the square of the amplitude of the oscillations. This is a Lorentzian function, and this response is found in many physical situations involving resonant systems. Î³ is a parameter dependent on the damping of the oscillator, and is known as the linewidth of the resonance.
