FIGURE Q17.3 shows the displacement of a standing sound wave in a 32-cm-long horizontal tube of air open at both ends.

a. What mode (m-value) is this?b. Are the air molecules moving horizontally or vertically? Explain.c. At what distances from the left end of the tube do the molecules oscillate with maximum amplitude?d. At what distances from the left end of the tube does the air pressure oscillate with maximum amplitude?
