Consider a musical instrument that can be regarded as a long pipe with both ends closed (see Fig. 1). Let the pipe length L=0.250 m. Closed ends mean that you should have nodes at the two ends. Assume sound speed to be v=330 m/s.

Problem 4 [8 pts] A long pipe, length L, is closed at both ends, and filled with a gas with speed of sound v. The pipe is excited in some fashion in order to produce standing waves. (a) Sketch the standing wave pattern for the four lowest frequencies supported by this pipe. Label the nodes and antinodes. (b) Make a table of the wavelengths and frequencies of the sound waves that are formed by these four excitations, in terms of...
An organ pipe open at both ends is 1.5 m long. A second organ pipe that is closed at one end and open at the other is 0.75 m long. The speed of sound in the room is 330 m/s.

Pipe A, which is 2.40 m long and open at both ends, oscillates at its third lowest harmonic frequency. It is filled with air for which the speed of sound is 343 m/s. Pipe B, which is closed at one end, oscillates at its second lowest harmonic frequency. This frequency of B happens to match the frequency of A. An x axis extends along the interior of B, with x = O at the closed end. (a) How many nodes...
Suppose a certain musical instrument consists of a pipe which is open at one end and closed at the other. Music is produced as sound waves move through the pipe, creating standing wave patterns. The pipe has a length of 80 cm. Q1) Find the wavelength of the first, third, and fifth harmonics (show your work). Q2) Find the frequency of the first, third, and fifth harmonics (show your work). Q3) Suppose you were riding your bike at 18 m/s...
Let's consider a pipe of length 45.0 cm open at both ends. What is the number of the highest harmonic that may be heard by a person who can hear frequencies from 20 Hz to 20,000 Hz? The speed of sound is 344 m/s. Sample submission: 12 Note for credit: if the pipe is closed at one end, then n = 103

A drainage pipe running under a freeway is 33.0 m long. Both ends of the pipe are open, and wind blowing across one end causes the air inside to vibrate. If the speed of sound on a particular day is 340 m/s , what will be the fundamental frequency of air vibration in this pipe? What is the frequency of the lowest harmonic that would be audible to the human ear? (The lowest frequency we can hear is about 20...
