5 A tube closed at one end has a vibrating diaphragm at the other end which may be assumed to be a displacement node It is found that when the frequency of the diaphragm is 2000 Hz a stationary wave pattern is set up in which the distance between adjacent nodes is 8 cm When the frequency is gradually reduced the stationary wave pattern disappears but another stationary wave pattern reappears at a frequency of 1600 Hz Calculate a the speed of sound in air b the distance between adjacent nodes at a frequency of 1600 Hz c the distance between the diaphragm and the closed end
