Resonant+Frequency

//By Sunil//

- The natural vibrating frequency of a system. - The relatively large selective response of an object or a system that vibrates in step with an externally applied vibration.

A child's playground swing is an example of a pendulum, a resonant system with only one resonant frequency. With a tiny push on the swing each time it comes back to you, you can continue to build up the amplitude of swing. If you try to force it to swing a twice that frequency, you will find it very difficult.

Swinging a child in a playground swing is an easy job because you are helped by its natural frequency.



The natural frequency of a system is the frequency at which the system wants to oscillate or vibrates once it has been set into motion. Resonance is when the amplitude of system’s oscillation or vibration builds up due to external stimulus at a specific frequency. A resonant frequency is any frequency at which resonance occurs. Some systems can experience resonance can at more than one frequency. Such systems often experience resonance at their natural frequency and its harmonics.
