Question

We are able to see the T.V. channels clearly when we set T.V. on auto-tuning.

1. Which phenomemon led to the clear visibility of the channels, due to auto-tuning?
2. Define the above phenomenon mentioned by you.
3. Give any one more example of this phenomenon.

Answer 1

1. Channels become clearly visible when resonance occurs.
2. Resonance is a particular type of forced vibration that is defined as a loud sound produced when the frequency of the applied force is either equal to or an integral multiple of the body's natural frequency and vibrates with maximum amplitude.
3. When the frequency of an oscillating disc matches the broadcasting station's natural frequency, radios are tuned to different channels.
