Definition of resonant frequency. : a frequency capable of exciting a resonance maximum in a given body or system.
A harmonic is any of the integer multiplications of the fundamental frequency. The fundamental frequency (f) is known as the first harmonic, and 2f is known as the second harmonic, and so on. A highly useful application of harmonics is the Fourier analysis. harmonic is any of the integer multiplications of the fundamental frequency.
