Set allowing you to perform experiments in wave optics on wavelengths on a centimetre scale.
A conical antenna transmitter emits a narrow beam of electromagnetic waves of linear polarisation with a wavelength of approx. 3 cm. To change the direction of polarisation, turn the conical antenna on the axis of the direction of propagation. The waves are revealed by a conical antenna receiver or a microwave probe. The service apparatus converts the received signal strength into a proportional output voltage that can be measured with a voltmeter. In addition, you can activate an acoustic signal whose volume is proportional to the intensity.
