The correct Answer is:
To solve the question, we need to analyze how antennas work in the context of AM broadcasting and the nature of electromagnetic waves. ### Step-by-Step Solution: 1. **Understanding Antennas**: - Antennas are devices that transmit and receive electromagnetic waves. In this case, we have a vertical telescopic transmitting antenna and a vertical telescopic receiving antenna. 2. **Nature of Electromagnetic Waves**: - Electromagnetic waves consist of two components: an electric field (E) and a magnetic field (B). These two fields oscillate perpendicular to each other and to the direction of wave propagation. 3. **Response of the Receiver**: - The receiver antenna is designed to respond to the electromagnetic waves transmitted by the broadcasting antenna. It can interact with both the electric and magnetic fields of the wave. 4. **Dominant Component for Reception**: - In practical applications, particularly for AM (Amplitude Modulation) broadcasting, the receiver primarily responds to the electric component of the electromagnetic wave. This is because the electric field induces a current in the receiving antenna, allowing it to convert the electromagnetic energy into electrical signals. 5. **Conclusion**: - Therefore, the correct answer to the question is that the receiver will respond to the electric component of the electromagnetic wave produced by the antenna. ### Final Answer: The receiver will respond to the **electric component of the electromagnetic wave produced by the antenna** (Option 1). ---
