If air is replaced by hydrogen in an organ pipe then

Organ pipes

A certain organ pipe resonates in its fundamental mode at a frequency of 500 Hz in air. What will be the fundamental frequency if the air is replaced by hydrogen at the same temperature? The density of air is 1.20kgm^-3 and that of hydrogen is 0.089 kgm^-3 .

An organ pipe is in resonance with a tuning fork. What change will have to be made in the length l to maintain resonance if (i) temperature increases (ii) air is replaced by hydrogen (iii) pressure is made higher ?

The harmonics formed in air column in an organ pipe closed at one end are

Compare the length of a closed organ pipe and an open organ pipe, if the second overtone of the open pipe is unison with the second overtone of the closed organ pipe.
