The experiment aims to determine the frequency and wavelength of a rectangular waveguide operating in the TE10 mode. An input signal is generated and passed through the waveguide. The frequency is measured using a frequency meter by observing dips in power. The guide wavelength is calculated by measuring the distance between maxima or minima of the signal along the slotted section of the waveguide. Cutoff wavelength is calculated using the inner dimension of the waveguide. Free space wavelength and frequency are then determined using the measured values and relationships between guide wavelength, cutoff wavelength, and free space wavelength. The experiment is repeated for different frequencies and the results are analyzed.
