Tuning of a radio set is an example of resonance:
Correct answer: A. Electrical
- A. Electrical
- B. Mechanical
- C. Free
- D. All of these
Explanation
Tuning a radio matches the receiver circuit's natural frequency to the frequency of the incoming signal - an example of electrical resonance.

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.
