The air in a tube open at both ends is made to vibrate in its fundamental frequency. One end of the tube is then closed and the air column is again set vibrate in its fundamental frequency. How do you compare the fundamental frequency (f1 open) of the tube open at both ends and the fundamental frequency (f1 closed) of the tube closed at one end? f1 open is equal to f1 closed f1 open is four times f1 closed f1 open is half of f1 closed f1 open is two times f1 closed

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.
