A bass clarinet can be modeled as a 120-cm-long open-closed tube. A bass clarinet player starts playing in a 20∘C room, but soon the air inside the clarinet warms to where the speed of sound is 352 m/s.
What is the change in frequency?
Homework Answers
L = length of the pipe = 120 cm = 1.20 m
T = room temperature = 20
V = speed of sound at room temperature = 331.4 + 0.6 T = 331.4 + 0.6 x 20 = 343.4 m/s
frequency at T = 20 is given as
f = V/(4L) = 343.4 /(4 x 1.20) = 71.5 hz
at V' = 352 m/s
frequency is given as
f' = V'/(4L) = 352/(4 x 1.20) = 73.3 hz
Change in frequency = f' - f = 73.3 - 71.5 = 1.8 hz

The clarinet is well modeled as a cylindrical pipe that is open at one end and closed at the other. Find the wavelength and frequency of the third normal (i.e. allowed) mode of vibration of a clarinet's air column with effective length of 0.399 m. Take 344 m/s for the speed of sound inside the instrument. Wavelength: Note: The third normal (allowed) mode is not necessarily the third harmonic depending on the boundary conditions for the pipe's ends. Number Frequency:...

A tube, open at the left end and closed at the right, has standing-wave patterns at frequencies of 198 Hz and 330 Hz. The speed of sound in air is 343 m/s. The lowest two harmonics (normal modes) that these two standing waves could be are m = and The frequency of the fundamental (m = 1) is Hz. The wavelength of the fundamental mode is m. The tube is m long

Ralph’s ear canal is 2.79 cm long. If it is regarded as a tube that is open at one end and closed at the eardrum, what is the fundamental frequency (Hz) around which we would expect hearing to be most sensitive? Consider the anti-node of a standing wave in the ear canal to occur exactly at the end of the canal. Use 345 m/s for the speed of sound in air

The human ear canal has a typical length of about 2.2 cm and can be modeled as a tube open at one end and closed at the eardrum. a) Calculate the fundamental frequency that humans should be expected to hear best. Assume that the speed of sound is 345 m/s in air. Looking deeply down your friends throat, or perhaps looking at a photograph, you observe the vocal tract. At the bottom of the vocal tract, when you aren't swallowing,...

A 0.75m long instrument tube has two open sides as a standing sound wave moves through it (speed of sound is 343 m/s). You count 4 nodes in the tube. (a) Find the wavelength and frequency. (b) You suddenly close both ends of the tube. The number of nodes doesn't change, but their positions do What is different about the air pressure and displacement? How did the wavelength and frequency change?
