Reson

Resonance is a phenomenon that occurs when a system naturally vibrates at a specific frequency and is driven by an external force matching that frequency. When this happens, the system's vibrations become more intense or amplified. An everyday example is pushing someone on a swing: if you time your pushes to match the swing’s natural rhythm, the swing goes higher. In physics and engineering, resonance can be useful, like in musical instruments or radios, but it can also cause problems, such as structures vibrating excessively during earthquakes. Understanding resonance helps in designing systems to either utilize or avoid these effects.
