Introduction
The LEEI-60 Experimental Apparatus for Transmission and Reception of Electromagnetic Waves is designed for teaching concepts related to electromagnetic oscillation and wave phenomena in general physics. This apparatus offers a practical and affordable tool for physics laboratories in colleges and universities, enabling students to explore fundamental principles of wave transmission, reception, and modulation.
With the LEEI-60 apparatus, students can observe and analyze the following phenomena:
1. Transmission of Electromagnetic Waves: Learn the principles of wave propagation.
2. Reception of Electromagnetic Waves: Understand how waves are detected and processed.
3. Transmitting Antenna Efficiency: Examine how the design and position of antennas impact transmission efficiency.
4. Resonance and Tuning: Study resonance in electric circuits and how tuning enhances signal reception.
5. Amplitude Modulation and Demodulation: Explore modulation, detection, and the principles of wave encoding for communication systems.
