In the experiment P3.7.4.3, standing microwaves are generated by reflection at a metal plate. The intensity, measured at a fixed point between the horn antenna and the metal plate, changes when the metal plate is shifted longitudinally. The distance between two intensity maxima corresponds to one half the wavelength. Inserting a dielectric in the beam path shortens the wavelength.
