Principle

If a double-slit is positioned in the divergent microwave beam, a characteristic intensity profile results behind this double-slit. The periodicity of the intensity profile can be used to determine the wavelength of the microwaves that are used.

Benefits


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


Tasks

First the phenomenon of diffraction through a single-slit and on a small obstacle is investigated. Then the intensity profile that results from a diffraction through a double-slit is measured and the wavelength of the electromagnetic wave that is used, based on this intensity profile, is determined.
