Microwave Interferometer
One of the most important turning points in Physics was the Mitchelson Morely Experiment, which implied that light did not need a medium to propagate.
The microwave interferometer instructs students on the basics of this experiment, and the box contains support material which explores the famous experiment. Additionally, included in the box is a double-slit apparatus, which can be used to find the wavelength of the microwaves using Young’s Slits equation.
