(i) Two cylindrical pipes are each of length L = 30 cm . One of them contains hydrogen and the other has oxygen at the same temperature. The ends A, B, C and D of the pipes are fitted with flexible diaphragms. The diaphragms A and C are set into oscillations simultaneously using the same source having frequency f = 600 Hz . Calculate the difference in phase of oscillations of the diaphragms D and B if it is known that the speed of sound in hydrogen at the temperature concerned is 1200 m//s .
