Question

What conditions are necessary to produce resonance in an object?

• A. The object must have at least one natural frequency of vibration.
• B. The object must be driven by an external vibrating force.
• C. The frequency of the external vibrating force must match the object's natural frequency of vibration.
• D. All of the above.

Answer 1

The correct option is D All of the above.

Resonance is a phenomenon in which the periodic oscillatory force acting on an object has a frequency of vibration same as the natural frequency of the object. In this, the object vibrates with a large amplitude.
