Interference, Diffraction & Polarization of Microwave - Basic

        
Interference, Diffraction & Polarization of Microwave
          
Introduction

Microwave and light wave 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 larger than that of a visible light wave, the experimental phenomena and apparatuses of microwave are different.

 

This LEEI-61 microwave demonstrator consists of a microwave transmitter,a microwave receiver with amplifier,a receiving dipole with other accessories. It can be used to demonstrate many interesting microwave experiments as follows:

 

1. Relay of microwave

2. Transmission and absorption of microwave

3. Microwave as polarized wave

4. Reflection of microwave on a metal plate

5. Refraction of microwave

6. Interference of microwave

7. Formation of standing electromagnetic wave

8. Diffraction of microwave

9. Directive transmission of microwave

10. Doppler effect
