An open pipe 30 cm long and a closed pipe 23 cm long, both of the same diameter, each sound their first overtone. If they are in resonance, find the end correction of these pipes.
Define end correction of a pipe. Prove that both odd and even types of harmonics can be obtained from an organ pipe at both ends.
Why is an end correction necessary for an organ pipe?
In a resonance air column apparatus, the first and second resonance positions were observed at 18cm and 56cm respectively. The frequency of the tuning fork used was 480 Hz. Calculate the velocity of sound in air and end correction of the tube.
