A 515-Hz tuning fork is struck and placed next to a tube with amovable piston, creating a tube with a variable length. The pistonis slid down the pipe and resonance is reached when the piston is112.5 cm from the open end. The next resonance is reached when thepiston is 82.5 cm from the open end. Round all answers to onedecimal place.
Hint (a)
- What is the speed of sound in the tube?
v=v=Â Â m/s - How far from the open end will the piston cause the next modeof resonance?
L=L=Â Â cm
