A Physics student wants to build a flute. He uses a pipe with two open ends. Before the student drills in holes, the tone played has a frequency of f=468Hz. What must be the length of the pipe if the speed of sound is V=343 m/s. (Please write your result in cm and with 1 decimal)

A sound wave has an intensity level of 121.3 dB in air. The density of air at 20.0°C is ρ = 1.20 kg/m3 (see Table 9.1). The speed of sound in air at 20.0°C is v = 343 m/s (see Table 12.1).   What is the pressure amplitude of the wave?

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.

A flute (open at both ends) plays a fundamental frequency of 196 Hz. The length of the air column is 89.2 cm. What is the speed of the wave resonating in the flute?

An organ pipe (L = 3.5 m) is closed at one end. Compute the wavelengths and frequencies of the first three modes of resonance. Assume the speed of sound is v = 343.00 m/s. fi : Hz f3 Hz f5 = Hz

The speed of sound in a solid medium is given by ?=?/?‾‾‾‾√v=E/ρ where ?E is the value of Young's modulus for the solid and ?ρ is the density.  A sound wave travels at 5.8×1035.8×103 m/s in a steel rod of length 1.11 m, diameter 2.0 cm and mass 7.0 kg.  Use the data to determine the value of the Young's modulus for steel. Give your answer in giga-pascal (GPa, 109 Nm-2).

Suppose you want to build a musical instrument with a hollow pipe that is open at one end and closed at the other.  You will make it oscillate by blowing  air across one end.  If it has length 0.2.  What frequency will it resonate at in Hz?  Assume the speed of sound in warm moist air is 340 m/s?

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 rope has a mass of 1 kg and a length of 15 m. It is fixed at both ends. If the frequency of the first harmonic on this rope is 0.68 Hz, what is the tension of this rope in N? Enter a number with one digit behind the decimal point.

What is the length in meters of a closed organ pipe with a fundamental frequency of 27 Hz? State your answer to the nearest m. The speed of sound in air is 343 m/s.
