ADamping a system until it stops
BDriving a system at its natural frequency
CDriving a system far above its frequency
DReflecting a sound wave off a hard wall
Answer & Solution
Correct answer: B. Driving a system at its natural frequency
1. Resonance is about matching a driving frequency to the system being driven.
2. Driving a system at a frequency equal to its natural frequency is called resonance.
3. A system driven that way is said to resonate, and its amplitude grows with each cycle.
4. Sing into a piano with the sustain pedal down and the matching strings sing back.
