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.

Calculate the frequency of a sound wave in helium if its displacement amplitude is 3.6 x 10-10 m and the pressure amplitude is 7.2 x 10-5 N/m². The density of helium is 0.166 kg/m³ and the speed of sound in helium is 2660 m/s. Answer in units of Hz.

The fundamental frequency of an organ pipe, closed at one end, is 286.3 Hz. What should the length of this organ pipe be (in cm)? Speed of sound in air at T = 20.0°C is 343 m/s. What is the fundamental frequency of this organ pipe if the temperature drops to 4.50°C?

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).

A piccolo and a flute can be approximated as cylindrical tubes with both ends open. The lowest fundamental frequency produced by one kind of piccolo is 544.3 Hz, and that produced by one kind of flute is 263.8 Hz. What is the ratio of the piccolo's length to the flute's length?

A piccolo and a flute can be approximated as cylindrical tubes with both ends open. The lowest fundamental frequency produced by one kind of piccolo is 587.3 Hz, and that produced by one kind of flute is 261.6 Hz. What is the ratio of the piccolo's length to the flute's length?

The lowest frequency in the audible range is 20 Hz. What are the lengths of (a) the shortest open-open tube and (b) the shortest open-closed tube needed to produce this frequency?
