Question

A long tube contains air at a pressure of 1 atm and a temperature of $$107^{o}C$$. 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 distance 19, 58.5 and 98 cm from the open end
The speed of sound at $$107^{o}C$$ is

A

495 m/s

Q3

A piston is fitted in a cylindrical tube of small cross section with the other end of the tube open. The tube resonates with a tuning fork of frequency 512 Hz. The piston is gradually pulled out of the tube and it is found that a second resonance occurs when the piston is pulled out through a distance of 32.0 cm. Calculate the speed of sound in the air of the tube.
