Definition of resonant frequency. : a frequency capable of exciting a resonance maximum in a given body or system.
Resonance is a condition in which a vibrating system responds with maximum amplitude to a periodic driving force.Mechanical systems will have a number of possible frequencies at which this occurs. These are the system's natural frequencies of vibration.t breaks. So, the resonance frequency is the frequency with which some external source must exert a force (swinging legs, sound wave, wind pushing a bridge, etc.) so that each application of the force adds constructively.
