When the frequency of the applied force becomes equal to one of the natural frequencies of the body then the body oscillates with maximum displacement this phenomenon is called:
Correct answer: B. Resonance
- A. Heating
- B. Resonance
- C. Reverberation
- D. Damping
Explanation
Option B is correct. Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force is equal or close to a natural frequency of the system on which it acts.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
