Question

1. If a wind instrument, such as a tuba, has a fundamental frequency of 30.1 Hz, what is its first overtone? It is closed at one end and the speed of sound is 334 m/s.

2. Find the length of an organ pipe closed at one end that produces a first overtone frequency of 276 Hz when air temperature is 21.3ºC .

3. A “showy” custom-built car has two brass horns that are supposed to produce the same frequency but actually emit 266.7 and 260.3 Hz. What beat frequency is produced?

**Plz answer all questions. don't have money for more,
will give thumbs up :)**

Answer #1

Solution -

2. Ans L= 0.933 m.

Solution -

3.

Solution -

The beat frequency is the absolute value of the difference of the two frequencies -

A. What length should an oboe have to produce a fundamental
frequency of 244 Hz on a day when the speed of sound is 343 m/s? It
is open at both ends.
B. What frequency is received by a person watching an oncoming
ambulance moving at 119 km/h and emitting a steady 706 Hz sound
from its siren? The speed of sound on this day is 333 m/s.
C. What energy in millijoules falls on a 0.808 cm diameter
eardrum...

The fundamental frequency of an organ pipe, closed at one end,
is 255.6 Hz.
a)What is the fundamental frequency of this organ pipe if the
temperature drops to 1.20°C? (Hz)
The fundamental frequency of an organ pipe, open at both ends,
is 278.9 Hz.
b) What is the fundamental frequency of this organ pipe if the
temperature drops to 1.00°C?

1. A spectator at a parade receives an 907 Hz tone from an
oncoming trumpeter who is playing an 877 Hz note. At what speed is
the musician approaching if the speed of sound is 345 m/s?
2. If a wind instrument, such as a tuba, has a fundamental
frequency of 34.6 Hz, what is its fifth overtone? It is closed at
one end and the speed of sound is 331 m/s.
3. A sonar echo returns to a submarine...

1. A sonar echo returns to a submarine 0.7 s after being
emitted. What is the distance to the object creating the echo?
(Assume that the submarine is in sea water, and therefore,
vw ≈ 1,522 m/s.)
2. If a wind instrument, such as a tuba, has a fundamental
frequency of 35.4 Hz, what is its fifth overtone? It is closed at
one end and the speed of sound is 337 m/s.

A. What is the intensity in 10-4 watts per meter
squared of 112 dB sound?
B.A spectator at a parade receives an 886 Hz tone from an
oncoming trumpeter who is playing an 863 Hz note. At what speed is
the musician approaching if the speed of sound is 336 m/s?
C. What frequency is received by a person watching an ambulance
moving away at 89 km/h and emitting a steady 774 Hz sound from its
siren? The speed of...

A stretched string can oscillate in resonance at 1280. Hz and at
1536 Hz. There are no resonance frequencies between the
frequencies.
a. what is the fundamental resonance frequency of the
string?
b. what is the length of an organ pipe, open at both ends, that
has the same fundamental frequency as the string? (Assume that the
velocity of the sound in air is 343.0 m/s)
c. Would the organ pipe of part (b) also be capable of resonance
at...

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...

Two identical pipes,
each closed at one end, have a fundamental frequency of 349 Hz at
20.0°C. A) What is the length of the pipes? B) If the air
temperature is increased to 25.0°C in one pipe what is the new
fundamental frequency in this pipe? C) If the two pipes are now
sounded together, what beat frequency results?

An organ pipe open at both ends is to be designed so that the
fundamental frequency it plays is 220 Hz.
a. What length of pipe is needed?
b. If one end of the pipe is stopped up, what other note
(frequency) can this same pipe play?
c. Draw the fundamental frequency for the pipe open at both ends
and when it is closed at one end.
d. Calculate and draw the next higher harmonic when one end of
the...
