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.

Previous Answers
Correct
Correct answer is shown. Your answer 805.9 Hz was either rounded differently or used a different number of significant figures than required for this part.
Because helium is less dense than air and has a lower molar mass, sound waves propagate faster in helium than in air. Thus, the frequencies produced in
the pipe when it is filled with helium are higher than those produced in the same pipe filled with air.
Part B
Now consider a pipe that is stopped (i.e., closed at one end) but still has a fundamental frequency of 275 Hz in air. How does your answer to Part A, ƒHe, change?

A tube 0.8 m long is closed at one end. A stretched wire is placed near the open end. The wire is 0.33 m long and has a mass of 9.6 g. It is fixed at both ends and oscillates in its fundamental model. By resonance, the vibrating string causes the air column in the tube to oscillate at the column's fundamental frequency.
