The intensity of a source of radiation, e.g. a microwave transmitter, at any given location depends on the distance of this location from the (approximately punctiform) source. Actually, due to its antenna geometry, a microwave transmitter can only be regarded as a punctiform source of radiation at long distances, which is why it is described as a virtual source for shorter distances.
- Convenient all-in-one set includes control unit, transmitter and receiver as horn antennae, microwave probe, microwave benches, grating, slit plates, prism, and reflection/absorption plates
- With the same set, all aspects of microwave physics can be studied quantitatively: polariziation, reflection, transmission, refraction, propagation, diffraction, interference, inverse square law, standing waves, conservation of energy in reflection and transmission
- Very detailed experiment guides for all experiments
The radiation intensity of the microwave transmitter is measured for various distances and the position of the virtual source is determined.
