Resonance is when a physical system exhibits a natural frequency of vibration that matches the external driving frequency. This means that the system naturally oscillates at that frequency, regardless of any external forces. Think of it as the system's inherent frequency resonating with the external input.
Example: Consider a mass attached to a spring. If the mass is not heavy enough to overcome the restoring force of the spring, then its natural frequency will be determined solely by the spring constant. If you increase the weight of the object, the natural frequency will decrease because the restoring force will be greater. This is an example of how the resonant frequency can be changed by varying the mass or the spring constant.
Key Points:
Resonant frequency is the frequency of natural vibration.
Resonance occurs when the driving frequency matches the natural frequency.
Resonance is independent of the amplitude of the driving force.
Resonance can be observed in various physical systems, including mass-spring systems, strings, and fluids
