A 503-Hz tuning fork is struck and placed next to a tube with a movable piston, creating a tube with a variable length. The piston is slid down the pipe and resonance is reached when the piston is 105 cm from the open end. The next resonance is reached when the piston is 75 cm from the open end. Hint (a) a. What is the speed of sound in the tube? V= m/s b. How far from the open end will the piston cause the next mode of resonance? L= cm
