(Loyd pre-lab #22 applies). In this experiment, the students will produce standing waves from sound waves in a resonance tube. A tube partially filled with water will serve as the resonance tube. A digital function generator and speakers will be used to produce sound waves in the resonance tube. The students will determine the following: several effective lengths of the closed tube at which resonance occurs for each frequency, the wavelength of the generated function from the effective length of the resonance tube, and the speed of sound from the measured wavelengths and known generated function frequencies. The measured speed of sound will be compared to the known value.
