Introduction
Microwaves and light waves, as electromagnetic waves, exhibit shared phenomena such as reflection, refraction, polarization, interference, and diffraction. However, the significantly longer wavelength of microwaves (approximately 4 orders of magnitude larger than visible light) necessitates specialized experimental setups and equipment.
The LEEI-61 Microwave Demonstrator is a comprehensive apparatus designed for exploring fundamental microwave phenomena in physics laboratories. It includes a microwave transmitter, a microwave receiver with an amplifier, a receiving dipole, and additional accessories. With tools like a protractor, ruler, multimeter, or oscilloscope, students can perform a range of engaging and educational experiments.
This apparatus allows for the following experiments and measurements:
1. Relay of Microwave: Observe microwave relay phenomena.
2. Transmission and Absorption: Study the interaction of microwaves with various materials.
3. Microwave as a Polarized Wave: Investigate polarization characteristics.
4. Reflection on a Metal Plate: Analyze reflection properties of microwaves.
5. Refraction of Microwave: Examine the bending of microwaves at material interfaces.
6. Interference of Microwave: Explore constructive and destructive interference.
7. Formation of Standing Electromagnetic Waves: Investigate standing wave patterns.
8. Diffraction of Microwave: Study the bending and spreading of waves around obstacles.
9. Directional Transmission: Measure the directional characteristics of microwave transmission.
10. Doppler Effect: Demonstrate and understand the frequency shift due to relative motion.
The accompanying instruction manual provides detailed experimental configurations, theoretical explanations, step-by-step procedures, and sample results to ensure a comprehensive understanding of each phenomenon. Please click Experiment Contents to find more information about this apparatus.
