You are trying to design a musical instrument that consists of a pipe filled with air at 20oC, so that it produces two successive harmonics that have frequencies of 240 Hz and 280 Hz. The speed of sound in air at 20oC is 343 m/s. (a) Should the pipe be open at both ends, or closed at one end? Justify your response

In the figure, S is a small loudspeaker driven by an audio oscillator and amplifier, adjustable in frequency from 1300 to 2400 Hz only. Tube D is a piece of cylindrical sheet-metal pipe 50.0 cm long and open at both ends. (a) If the speed of sound in air is 344 m/s at the existing temperature, at how many frequencies will a resonance occur in the pipe when the frequency emitted by the speaker is varied from 1300 Hz to 2400 Hz? (b) What is the lowest resonant frequency in the given interval? (a) Number Units (b) Number Units

A tuning fork is held over the top of a graduated cylinder that is slowly filled with water. Two resonances are noted as the cylinder is filled. They occur when the water level is 56.5 cm and 17.5 cm below the rim. Note that there is an end correction, meaning that the effective length of the air column is longer than the observed length by a fixed constant amount. If the speed of sound is 343 m/s, find the frequency of the tuning fork.

A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (a) What is the speed of sound in the flute? A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (b) What is the wavelength of the first harmonic? Consider the flute to be a pipe open at both ends  A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. (c)Consider the flute to be a pipe open at both ends and find its length, assuming this frequency is the fundamental frequency A flute is designed so that it plays a frequency of 268.2 Hz, when all the holes are covered and the temperature is 18.2°C. A second player, nearby in a colder room, also attempts to play middle C on an identical flute. A beat frequency of 3.00 beats/s is heard.  (e) What is the speed of sound in the second room? A flute is designed so that it plays a…

A pipe has a length of 0.582 m and is open at both ends. Take the speed ofsound to be v = 343 m/s.(a)Calculate the two lowest harmonics of the pipe (in Hz).(b)Calculate the two lowest harmonics (in Hz) after one end of the pipe is closed.

(a) At T=12oC, how long must an open organ pipe be to have a fundamental frequency of 300 Hz? (b) If this pipe is instead filled with helium at 20oC , what is its fundamental frequency?

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?

A pipe of length A has two open ends. Another pipe of length B has one open end and one closed end. The frequency of the first harmonic of both pipes is the same. What is (A/B)?
