(a) Refraction

(b) Forced vibration

(c) Resonance

(d) Diffraction.

To determine

The correct option for the statement “When your radio set is tuned to an incoming radio signal, what is occurring”.

Answer to Problem 7RAT

The correct option for the statement “When your radio set is tuned to an incoming radio signal, what is occurring” is option (c).

Explanation of Solution

When the frequency of forced vibrations imposed on an object matches the object’s natural frequency, a dramatic increase in amplitude occurs. This phenomenon is called resonance. In order to resonate, it needs a force to pull it back to its starting position and enough energy to keep it vibrating.

When you tune your radio, you adjust the natural frequency of the electronics in the radio that match one of the many surrounding signals in the air. The radio then resonates with one station at a time instead of playing all stations all at once. Refraction, reflection, or forced vibrations don’t act there.

Conclusion:

Therefore, correct option for the statement “When your radio set is tuned to an incoming radio signal, what is occurring?” is option (c).
