    Resonance describes the phenomena of amplification that occurs when the frequency of a periodically applied force is in harmonic proportion to a natural frequency of the system on which it acts When an oscillating force is applied at the resonant frequency of another system the system will oscillate at a higher amplitude than when the same force is applied at other nonresonant frequencies
