Abstract
The wavelength of a microwave transmitter was determined by using a method of interferometry called Lloyd's Mirror. This method consists of a transmitter, reflector, and a receiver. By relating the total path a wave travels, to the distance of a reflector away from the wave, the wavelength of said microwave can be calculated using a linear regression. Two sets of data taken are consistent in showing distance does not change wavelength despite the imprecision of the results when compared to the recorded wavelength of the microwave transmitter. Outside influences creating additional reflection are likely the cause of this imprecision.
