Question 5: What is resonance? Give three of its examples from our daily life.
ANSWER
There is always a marked increase in the amplitude of a vibrating body when an external force having the same time period as that of the natural time period of the body is applied to it. This phenomenon is called resonance.
It also occurs when the frequency of the applied force is an integral multiple of the natural frequency of the oscillating body, i-e, 2f, 3f, 4f …
