Two sound waves with an amplitude of 12 nm and a wavelength of 35 cm travel in the same
Chapter 17, Problem 89(choose chapter or problem)
Two sound waves with an amplitude of 12 nm and a wavelength of 35 cm travel in the same direction through a long tube, with a phase difference of p/3 rad. What are the (a) amplitude and (b) wavelength of the net sound wave produced by their interference? If, instead, the sound waves travel through the tube in opposite directions, what are the (c) amplitude and (d) wavelength of the net wave?
