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.

from the opening and the second is 45.0 cm, what is the frequency of this tuning fork?
c. After working really hard on a hot day a third tuning fork is used with a frequency of 1053 Hz,
and the distance between the 1 and 3d standing wave created is 33.0 cm, what is the
temperature of the air in this pipe?
