A tuning fork with a frequency of 256 Hz is held above a closed air column while the column is gradually increased in length. At what lengths for this air column would the first four resonant points be found, if the speed of sound is 330 m/s?

a vocal tract acts as an air column closed at one end. The vocal tract of a singer is 25.0cm long and its vibrating in the second overtone (3rd resonant length). if the speed of sound is 352 m/s, what frequency is the singer producing?

Two trumpets are being tuned using beats. One has a frequency of 440 Hz. When the second is played along with it, 15 beats are heard in 5.0 s. What are the possible frequencies of the second trumpet?

The longest pipe on a certain organ is 3.74 m. (a) What is the frequency f7 (at 0.00°C) if the pipe is closed at one end? 22.125 Your response differs from the correct answer by more than 10%. Double check your calculations. Hz (b) What is the frequency f7 (at 0.00°C) if the pipe is open at each end? 44.251 Your response differs from the correct answer by more than 10%. Double check your calculations. Hz (c) What will be the frequencies f7 at 20.0°C? pipe frequency (Hz) 22.927 closed Your response differs from the correct answer by more than 10%. Double check your calculations. 45.855 open Your response differs from the correct answer by more than 10%. Double check your calculations.

If the vocal tract of a human is considered a closed tube 17 cm in length, what is the frequency of what would become the second harmonic? Consider 340 m/s as the speed of sound. The answer must be in Hz units.

An organ pipe is open at both ends. It is producing sound at its n = 3 harmonic, the frequency of which is 164 Hz. Take the speed of sound to be 345 m/s. What is the length of the pipe?

A sound wave with a frequency of 9800 Hz travels along a copper pipe. If thewavelength is 0.370 m and the density of copper is 8.9 x 10^3 kg/m^3, what is the elastic modulus of copper?

The fundamental frequencies of two air columns are the same. Column A is open at both ends, while column B is open at only one end. The length of column A is 0.488 m. What is the length of column B?
