A
Increase in amplitude when driving frequency matches natural frequency
B
Decrease in amplitude of oscillations over time
C
The bending of waves around obstacles
D
Splitting of white light into colours
Correct Answer: Option A — Increase in amplitude when driving frequency matches natural frequency
Explanation:
Resonance occurs when a system is driven at its natural frequency causing the amplitude of oscillations to increase dramatically and can be seen in musical instruments and bridges.
