Question

what is resonance and state it's condition​

Answer 1

Answer:

Resonance meaning in English is ‘to sound’ that is to produce sound. To produce sound the body must vibrate with the same wavelength as that of the other. Example of resonance is the simple harmonic motion exhibited by the pendulum.

Explanation:

The definition of Resonance in physics is a phenomenon in which an external force or a vibrating system forces another system around it to vibrate with greater amplitude at a specified frequency of operation. The frequency at which the second body starts oscillating or vibrating at higher amplitude is called the resonant frequency of the body. The best examples of resonance can be observed in various musical instruments around us.

A classic example of resonance is the swinging of a person sitting on a swing. A swing is a very good example of an object in oscillating motion. Initially, the motion is slow and the swing doesn’t extend to its maximum potential. But once when the swing reaches its natural frequency of oscillation, a gentle push to the swing helps it maintain that amplitude of swing all throughout due to resonance.
