Sound we hear through our ears and its structure, free oscillation, damped oscillation and resonance with suitable examples

6. FREE OSCILLATION

7. FORCED OSCILLATION
• When a system is forced to oscillate at a frequency
other than its natural frequency, then it is called
Forced oscillation.

8. RESONANCE
When a frequency of a vibration on an
object matches the object’s natural
frequency, there is a dramatic increase in
height occurs.
This is called resonance and the frequency
gained by it is called resonant frequency.

9. High amplitude shows resonant frequency

12. DAMPED OSCILLATION
