Question: A long tube contains air at a pressure of 1.00 atm and a temperature of 77.0 C. The tube is open at one end and closed at the other by a movable piston. A tuning fork near the open end is vibrating with a frequency of 500 Hz. Resonance is produced when the piston is at distances 18.0, 55.5, and 93.0 cm from the open end

a) From these measurements, what is the speed of sound in air at 77.0 C?

b) From the result of part A, what is the value of Î³?

c) These data show that a displacement antinode is slightly outside of the open end of the tube. How far outside is it?

Express your answer using two significant figures.
