A person uses a 512 Hz tuning fork to find the first two resonant lengths of a closed air column in a very warm classroom. The first length measured was 17.1 cm and the second resonant length was 51.3 cm. (a) Draw diagrams to show the standing wave pattern in each length and indicate the length in wavelengths. (b) Calculate the wavelength of the tuning fork at that temperature. (c) Use the lab observations and analysis to find the speed of sound and the temperature of the room.
Interference of sound
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.
