A student must determine the speed of sound in air by using the fundamental frequency of a standing wave. 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. How should the student adjust the closed end of the pipe to determine the first standing wave that can be established in the pipe?
