Microwave and lightwave are both electromagnetic waves. They share common phenomena of all waves, such as reflection, refraction, polarization, interference, and diffraction. However, as the wavelength of a microwave is about 4 orders of magnitude larger than that of a visible lightwave, the experimental phenomena and apparatus of microwave are different.
This LEEI-62 experimental system of microwave interference, diffraction and polarization consists of a microwave transmitter with a variable attenuator, a microwave detector with amplifier and meter display, a transmitting horn and a receiving horn, as well as other accessories such as single slit, double slits, beam splitter, crystal model, etc. It can provide quantitative measurements of a series of experiments such as:
1. Verify reflection law of electromagnetic wave
2. Measure intensity distribution of single-slit diffraction
3. Measure intensity distribution of double-slit interference
4. Measure microwave wavelength through interference of Michelson interferometer
5. Study polarization and verify Malus' law
6. Verify Bragg diffraction of crystal model
