The standing wave properties of an ear canal are often modelled as a tube with one end open and one end closed. This is shown in the following diagram for a tube of length L = 2.1 cm. The fundamental mode for the sound-pressure standing wave is indicated.The standing wave properties of an ear canal are often modelled as a tube with one end open and one end closed. This is shown in the following diagram for a tube of length L = 2.1 cm. The fundamental mode for the sound-pressure standing wave is indicated.

a) What is the fundamental frequency?

b) Redraw the tube 3 times. Sketch in the standing wave patterns for the 2nd, 3rd and 5th harmonics.

c) What is the wavelength of the 5th harmonic?

d) What is the fundamental frequency if the ear was filled with water?

e) Consider a second tube that is open-open with length L2.

(i) Draw the standing wave pattern for the 3rd harmonic.

(ii) What is L2 so that the 3rd harmonic frequency equals the second harmonic frequency of the ear canal? (assume air-filled for both)

The frequencies of two successive higher harmonics of a standing sound wave in a closed-closed tube is 450 Hz and 600 Hz. There are no other frequencies in between these two. What are the frequencies of the fundamental (1st harmonic) and the second harmonic of this tube? Draw the standing wave pattern (with respect to pressure variation) of the second harmonic. Mark the nodes and anti-nodes.

Four standing waves, labeled A through D, are described below: Wave A: first harmonic; pipe closed at one end; length = 1 m Wave B: first harmonic; pipe open at both ends; length = 1 m Wave C: second harmonic; pipe open at both ends; length = 3 m Wave D: second harmonic; pipe closed at one end; length = 3 m Rank the standing waves in order of decreasing frequency. Rank from greatest to smallest. To rank items as...

A stove is connected to a stovepipe of length L=3m. When the wind blows, the pipe sometimes “sings” (just like blowing across the top of a coke bottle). The fundamental frequency and lowest few overtones are usually heard. Assume the speed of sound to be 300 m/s. a) Assume that the pipe is “open” on one end and “closed” on the other. Draw a displacement standing wave diagram for this case and determine the fundamental frequency of sound that is...

7) (a) Draw a diagram to represent the standing wave patterns for the first three harmonics of a pipe with one open end. (i) How many nodes and antinodes are there for each harmonic? (ii) What are the relations for the length of the rope L, the wavelength λ, and the frequency f of the standing waves?

for a string to form a standing wave, does the length of the string have to be in a multiple of 1/2 lambda or 1/4 lambda? what about for a tube with one open and and one closed end and a tube with two open ends. why is this the case for each scenerio?

You are playing a violin, where the fundamental frequency of one of the strings is 440 ??, as you are standing in front of the opening of a long tube that is closed at the other end. As you play, you notice that the first time you hear an echo from the tube is when the sound from the 440 ?? string is in its fourth harmonic. Assuming you are playing this string on earth, what must be the length...
