Question

How do you tune your radio set to a particular station ? Name the phenomenon involved in doing so and define it.

Answer 1

Resonance is the basis for radio tuning. You may alter the frequency of the electrical vibrations produced by them by adjusting the values of the individual components in the electronic circuits that make them up. Changing the values of a few electrical components causes vibrations at a frequency that matches the desired radio wave frequency, and that's all. When the two frequencies are in resonance with one another, the incoming waves carry the signal energy of the matching frequency. In the receiver set, the signal is then amplified.
