What is resonance? Give example for it. |

Answer» Solution :The frequency of exterrnal periodic FORCE (or driving force) matches with the frequency of the VIBRATING body (driven). As a result the oscillating body begins to vibrate such that its amplitude increases at each step and ultimately it has a large amplitude. Such a phenomenon is known as resonance and the corresponding VIBRATIONS are known as resonance vibrations. Example: The breaking of GLASS DUE to sound |
