A68.0 cm pvc pipe is open on both ends. use the speed of sound as 340 m/s. a draw snapshot graphs for the first five standing wave modes (graphs of pressure vs. position along the pipe). for each, label the nodes and antinodes and the distance that corresponds to the wavelength. b. use these drawings to determine the numerical value for the wavelength of each mode. c. calculate the frequency for each standing wave move. d. imagine that the one end of the 68.0 cm pvc is now closed. for each of the following quantities, identify whether it would increase, decrease, or stay the same. explain. a. wavespeed increase decrease stay the same b. wavelength increase decrease stay the same c. frequency increase decrease stay the same explain your reasoning: e someone plays the same pvc pipe, and a frequency of 1,375 hz is heard. was the pipe played the open-open condition or the open-closed conditions? how can you tell?
