A pipe from an organ is open at one end and closed at the other. The pipe is designed to produce the middle note C (frequency = 132 Hz) as its fundamental frequency. [speed of sound = 340 m/s] (a) How long is the pipe? (b) What is the frequency of the 3rd harmonic? (c) For the 3rd harmonic, how many nodes are found inside the pipe?
Interference of sound
Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
