In a first experiment, a sinusoidal sound wave is sent through a long tube of air, transporting energy at the average rate of Pavg,1. In a second experiment, two other sound waves, identical to the first one, are to be sent simultaneously through the tube with a phase difference f of either 0, 0.2 wavelength, or 0.5 wavelength between the waves.
