A hollow cylinder of length 1 m is divided by a thin flexible by a thin flexible diaphragm at a distance one-third the length of the cylinder. It is closed by two other flexible diaphragms at the ends. Of the two chambers into which it is divided, the longer one contains hydrogen and the other oxygen. The two end diaphragms are set into vibrations of the same frequency. what are the frequencies of the end diaphragms for which the middle diaphragm will be motionless? Velocity of sound in hydrogen =1100 m s^(-1) and that in oxygen =300 m s^(-1).

1.	A hollow cylinder of length 1 m is divided by a thin flexible by a thin flexible diaphragm at a distance one-third the length of the cylinder. It is closed by two other flexible diaphragms at the ends. Of the two chambers into which it is divided, the longer one contains hydrogen and the other oxygen. The two end diaphragms are set into vibrations of the same frequency. what are the frequencies of the end diaphragms for which the middle diaphragm will be motionless? Velocity of sound in hydrogen =1100 m s^(-1) and that in oxygen =300 m s^(-1).
