How to Find Resonant Frequencies | Sciencing

A resonant frequency is the natural vibrating frequency of an object and is usually denoted as a f with a subscript zero (f0). This type of resonance is found when an object is in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions.
