8) Consider a 0.676-m long tube, open at both ends. a) What is the fundamental resonance frequency, in hertz, of the tube on a day when the speed of sound is 344 m/s? b) What is the frequency, in hertz, of its second harmonic?
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.
8) Consider a 0.676-m long tube, open at both ends.
a) What is the fundamental resonance frequency, in hertz, of the tube on a day when the speed of sound is 344 m/s?
b) What is the frequency, in hertz, of its second harmonic?
The fundamental frequency is calculated using the formula f1 = v/(2L). where v is the speed of the sound wave, and L is the length of a tube.
The harmonic frequencies are integer multiples [2, 3, 4, ...] of the fundamental frequency.
