Food being cooked in a microwave oven is an example of :
Correct answer: C. Resonance
- A. Beats
- B. Overtones
- C. Resonance
- D. Stationary waves
Explanation
Resonance occurs when an external force matches the natural frequency of a system, leading to an increase in amplitude of vibrations. In the case of cooking food in a microwave oven, the microwaves generated match the natural frequency of water molecules, causing them to vibrate and generate heat through friction. This process is an example of resonance. Therefore, option c) is the correct choice.

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.
