What is resonance?
In A Level Physics, resonance refers to the phenomenon that occurs when the frequency of the force applied to an oscillating system is equal to its natural frequency, and the amplitude of the resulting oscillations increases significantly.
Resonance occurs because the energy added to the system by an external force matches the system's natural frequency of vibration, leading to a significant increase in energy absorption.
Resonance can be observed in various physical systems, including mechanical, electrical, and acoustic systems, and is crucial for understanding processes like tuning musical instruments, designing buildings to withstand earthquakes, and managing electrical circuits.
