2. A sound wave is travelling in a steel frane of a steel that has a Bulk modulus 160 GPa and den...
A steel pipe with length L has bulk modulus 1.6×1011 N/m2 and density 7860 kg/m3 . One end of the pipe is dealt a sharp blow with a hammer. A listener at the other end of the pipe hears two sounds: one from the wave traveling along the pipe and one from the wave traveling through the air. Find the length of the pipe, if the time interval between the two sounds is 1.45 s. Take the speed of sound...
Problem 1: A sound wave of the form s = Smax cos(kx - wt+ 0) travels at 343 m/s through air in a long horizontal tube. At one instant, air molecule A at x = 2.000 m is at its maximum positive displacement of 6.00 nm and air molecule B at x = 2.070 m is at a positive displacement of 2.00 nm. All the molecules between A and B are at intermediate displacements. (a) What is the wavelength of...
