Question

what is resonance give examples​

Answer 1

$\huge \text{Resonance }$

✍ 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 $\Large \text{Resonance. }$

$\huge \text{Examples }$

✍ 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.
