In physics, resonance is the phenomenon in which a vibratory system or external force causes another system to oscillate with greater amplitude at specific frequencies, known as resonant frequencies or natural frequencies of the system.  At these frequencies, even small periodic forces can produce large amplitude vibrations because the system stores vibrational energy.

 Systems have multiple and distinct resonant frequencies and this phenomenon occurs with all types of vibrations or waves;  mechanical (acoustic), electromagnetic, and quantum wave functions.  Resonant systems can be used to generate vibrations of a specific frequency, or to obtain specific frequencies from a complex vibration containing many frequencies.

 Resonance was discovered by Galileo Galilei when he began his research with pendulums and musical strings in early 1602. Others believe that Pythagoras pioneered the subject much earlier during his lifetime between 570 - 495 years BC especially in researching music theories.
