Equipment set for conducting wave optics experiments involving wavelengths in the cm range.
A transmitter with a horn antenna radiates a narrow beam of linearly polarised electromagnetic waves with a wavelength of about 3 cm.
The direction of polarisation can be altered by rotating the antenna around the axis of propagation.
To detect the waves, a horn antenna receiver and a microwave sensor are provided.
A control unit converts the intensity of the signal received into a proportionally large output voltage that can be measured using a voltmeter.
It is also possible to switch on an acoustic signal with a volume that is proportional to the intensity of the signal.
