What is resonance and what conditions cause it? Give examples
What will be an ideal response?
Resonance is an unusually large increase in amplitude when a system is driven at its natural frequency by an outside force. A good example is someone pushing another person on a swing. When the pushes are in rhythm with the natural swing motion, very soon the swing is high in the air with little effort by the person doing the pushing. Another example is the sounding of a tuning fork by the vibrations of another nearby fork of matched frequency. Another example is the destruction of a bridge when small pushes are applied in rhythm with the natural frequency of the bridge.
