Velocity of sound in air is 320m/s. A pipe closed at one end has a length of 1m. Neglecting the end corrections, the air column in the pipe can resonate for sound of frequency : the air column in the pipe can resonate for sound of frequency : Velocity of sound in air is 320m/s.

A pipe closed at one end has a length of 1m. Neglecting the end corrections, the air column in the pipe cannot resonate with sound of frequency :Velocity of sound in air is 320m/s. A pipe closed at one end has a length of 1 m. Neglecting the end corrections, the air column in the pipe can resonate for sound of frequency.An open pipe is in resonance in it 2nd harmonic with tuning fork frequency f1. Now it is closed at one end. if the frequency of the tuning fork is increased slowly from f1 then again a resonance is obtained with frequency f2. If in this case the pipe vibrate nth harmonic then
