Question

What is resonance ??​

Answer 1

$\bold{ANSWER}$

When the natural frequency of a body matches with the frequency of periodic force the body oscillates with the large amplitude. This phenomenon is called Resonance.  

In sonometer experiment, the paper rider placed on the stretched string between the knife edges flies off due to the resonant oscillations of the string when the stem of oscillating tuning fork is pressed on the top face of the sonometre box this happens when the frequency of wire between the knife edges matches with the frequency of tuning fork.

A loud sound is heard, due to the resonant oscillations of air column when the exited tuning fork is held at the open end of the pipe .This happens when frequency of air column matches with the frequency of tuning fork.

Hey mate

Resonance :- 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.

OR

Resonance :- In mechanical systems, resonance is a phenomenon that only occurs when the frequency at which a force is periodically applied is equal or nearly equal to one of the natural frequencies of the system on which it acts.
