Question

Explain resonance with suitable diagram.

Answer 1

Resonance is defined as the tendency of the system to oscillate at greater amplitude at some frequencies than at others.
It is common among the systems that have a tendency to oscillate at a particular frequency and that frequency is known as natural frequency.
It is common among the systems which have the tendency to oscillate at a particular frequency.
Examples:-

A pendulum oscillates at its natural frequency. If a push is given to pendulum its amplitude increases. This frequency with which pendulum oscillates with a greater amplitude is known as the resonance frequency.


Swing. A child when sitting on a swing, he swings at his natural frequency. But if someone gives a push to the swing from the behind at the same frequency with which the swing was swinging earlier. Then the amplitude increases ,this is known as resonance and frequency is known as resonant frequency.
