A student must determine the speed v of sound in air. The student places a tuning fork in front of the open end of a pipe that is closed at the other end. The closed end of the pipe can be adjusted so that the length of the pipe can be changed. The student varies the frequency of the sound in the pipe by holding tuning forks of different frequencies ff in front of the open end of the pipe. The student then measures the smallest length L of the pipe that creates a standing wave for several different tuning forks. Which of the following procedures can the student use to determine the speed of sound in air by using a best fit line? A-Graphing f as a function of L and finding that the slope of the graph is equal to v/2.

B-Graphing f as a function of L and finding that the slope of the graph is equal to v/4.

C-Graphing f as a function of 1/L and finding that the slope of the graph is equal to v/2

D-Graphing f as a function of 1/L and finding that the slope of the graph is equal to v/4
