Description: 

Microwave polarization

Instructions: 

Orient the receiving dipole antenna parallel to the direction of polarization and the electric field will create an potential difference between the dipole halves, detecting the signal. With the antenna oriented perpendicular no signal is detected.

Purpose: 
To show that microwaves emitted from the transmitter are polarized relative to the direction of the accelerated charges in the dipole antenna.
