Question
What phenomenon occurs when the frequency of a driving force matches or is near the natural frequency of an oscillating system, leading to a significant increase in the amplitude of oscillation?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The 'Forced Oscillations and Resonance' section on page 24 explains that 'This increase in amplitude near ω₀ is called resonance. Hence ω₀ is also called resonance frequency of the system.'
Hint
Think about what happens when an external force's frequency matches a system's natural frequency.
