Question

What conditions are necessary to produce resonance in an object?

Answer 1

Resonance is a phenomenon in which the periodic oscillatory force applied to an object has a frequency of vibration that matches the natural frequency of the object. In this, the object often vibrates with a huge amplitude. example of resonance: a vibrating rod made up of metal, forces the air column inside the rod to vibrate at similar frequencies. Many sounds we hear, like when hard objects of metal, glass, or wood are struck, are caused by brief resonant vibrations in the object.

Complete step-by-step solution:
Resonance represents the phenomenon of increased amplitude that comes out when the frequency of a periodically applied force is equal or near to a natural frequency of the system on which it applies.
The conditions to produce resonance in an object are:
The object must have a minimum of one natural frequency of vibration.
The object must be driven by an external force of vibration.
The frequency of the external vibrating force must be similar to the object's natural frequency of vibration.

Note: When an oscillating force acts at a resonant frequency of a dynamic system, the system will oscillate at a large amplitude than when the same force is applied at other, non-resonant frequencies. Frequencies at which the response amplitude is a relative highest are also known as resonant frequencies or resonance frequencies of the system. Little periodic forces that are close to a resonant frequency of the system can produce greater amplitude oscillations due to the storage of vibrational energy.
