BEX-8512 Comprehensive Microwave Optics System
| |||||||||||||
Details Principle Microwave refers to electromagnetic waves with a frequency of 300MHz-3000GHz. Although the generation, transmission, and reception of microwaves are quite different from the long-wavelength broadcasting and radio waves of television, they are also quite different from the light electromagnetic waves with extremely short wavelengths. However, the wave characteristics of electromagnetic waves such as diffraction, interference and polarization can also be clearly observed in microwave experiments, which is very helpful for us to understand the properties of microwave electromagnetic waves. The wavelength of microwaves is about 1000 times larger than that of light waves. Therefore, it is easier and more intuitive to use microwaves to conduct wave experiments than optical methods. Overview This experimental device uses the generation, transmission and reception of microwaves, cooperatewith the spectrometer structure and some accessories to study the microwave fluctuation characteristics. The microwave emitted from the signal source, after passing through the single/double slits, polarizing plate and other structures on the center platform, appears diffraction, interference, and polarization. The receiver receives the signal records it to verify the microwave fluctuation characteristics. Features
