A stretched string and an air column which is open at both ends are in resonance with each other. The air column is 55 cm. long, filled with air at room temperature (speed is 340 m/s), and is vibrating at its 3rd harmonic frequency. The string is 60 cm. long and has a total mass of 5 grams. If the string is vibrating in it's 4th harmonic frequency (and this matches the pipe’s third harmonic) a) what is the fundamental frequency of the vibrating air column in the pipe? b) what is the speed of the wave in the string? c) what is the tension in the string?

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.
