What is the condition for resonance in SHM?

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.

What does it mean by resonance in forced oscillator?

Resonance is a particular case of forced oscillation. When the frequency difference between the system and that of the external force is minimal, the resultant amplitude of the forced oscillations will be enormous. However, when the two frequencies match or become the same, resonance occurs.

How resonance is formed in forced vibration?

Objects that are free to vibrate have their natural frequencies in which they vibrate when left for a duration of time. Resonance occurs when objects are forced to vibrate at their natural frequency. The force will create vibrations of very large amplitude when object is vibrating at resonance.

Why does the resonance occur when frequency of forced oscillations is close to natural frequency?

Resonance occurs when frequency of forced oscillations is close to natural frequency. The reason for this increase in amplitude is that the vibrations of the external oscillator match with the vibrations of particles being oscillated and thus there is a net increase in vibrations.

What causes resonance?

Resonance only occurs when the first object is vibrating at the natural frequency of the second object. When the match is achieved, the tuning fork forces the air column inside of the resonance tube to vibrate at its own natural frequency and resonance is achieved.

What causes forced vibration?

Forced vibrations occur if a system is continuously driven by an external agency. A simple example is a child’s swing that is pushed on each downswing. Of special interest are systems undergoing SHM and driven by sinusoidal forcing.

What are forced oscillations class 12 physics?

Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system. In such a case, the oscillator is compelled to move at the frequency νD = ωD/2π of the driving force.

What is the main difference between forced oscillations and resonance?

The frequency of external periodic force is different from the natural frequency of the oscillator in case of forced oscillation but in resonance two frequencies are equal.

What affects resonance?

Resonance, An object free to vibrate tends to do so at a specific rate called the object’s natural, or resonant, frequency. (This frequency depends on the size, shape, and composition of the object.)
