What is the phenomenon of resonance in physics?

  • 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 ...
