E) wave interference.

Question

When you tune a radio to match the frequency of the desired station, you are using the principle of resonance. Resonance occurs when the frequency of an external force matches the natural frequency of a system, leading to an increase in amplitude of the system's oscillations. In the context of radio tuning, this principle allows the radio's internal circuit to selectively amplify the signal of the desired station.
