Question
What phenomenon occurs when the frequency of the driving force (ωd) is near the natural frequency (ω₀) of the oscillating system, leading to a very large amplitude?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The 'Resonance and Power Transfer' section on page 24 defines this: 'This increase in amplitude near ω₀ is called resonance. Hence ω₀ is also called resonance frequency of the system.'
Hint
Think about pushing a swing at just the right timing to make it go higher.
