Suppose a low brass instrument, such as a tuba, has a fundamental frequency of 30.5 Hz. Such instruments act like resonance tubes which are closed at one end, although their resonant frequencies are complicated because they are smaller at the mouth piece and larger at the bell end. For this problem, you may assume the instrument is a simple tube. a. What is its first overtone, in hertz? b. What is its second overtone, in hertz? c. What is its third overtone, in hertz?

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.
