Resonate

Definition

Resonate occurs when a system oscillates at its natural frequency due to an external periodic force. This results in a large amplitude of oscillation.

5 Must Know Facts For Your Next Test

1. Resonance happens when the frequency of the applied force matches the natural frequency of the system.
2. The amplitude of oscillation increases significantly during resonance.
3. Damping can reduce the amplitude of resonant oscillations but does not change the resonant frequency.
4. Resonance is observed in various physical systems, such as mechanical, electrical, and acoustic systems.
5. Examples include a swing being pushed at regular intervals matching its natural frequency and glass breaking due to a high-pitched sound.

• How does damping affect the amplitude and frequency of resonant oscillations?
• Provide an example of resonance from everyday life and explain why it occurs.
