Question

An organ pipe is 5.90 m long and is closed at one end. (The
speed of sound at *T* = 20.0°C is *v* = 343 m/s.)

What is the second lowest standing wave frequency for the organ pipe?

What is the third lowest standing wave frequency for the organ pipe?

What is the fourth lowest standing wave frequency for the organ pipe?

The sound level 23.2 m from a loudspeaker is 63.4 dB. What is the rate at which sound energy is produced by the loudspeaker, assuming it to be an isotropic source?

Answer #1

The sound level 22 m from a loudspeaker is 68 dB. What is the
rate at which sound energy is produced by the loudspeaker, assuming
it to be an isotropic source?

An organ pipe is 130 cm long. The speed of sound in air is 343
m/s. Part A What are the fundamental and first three audible
overtones if the pipe is closed at one end? Express your answers
using three significant figures separated by commas. Part B What
are the fundamental and first three audible overtones if the pipe
is open at both ends? Express your answers using three significant
figures separated by commas.

A 1.20 m long column of air in a pipe organ, that is closed on
only one side, plays its very low fundamental frequency. If the
temperature of the air is 22.4 degC, what is that frequency?
A string of length 0.0140 m is pulled across the top of the
column of air, and causes it to vibrate in its 2nd overtone, what
is the velocity of the wave on the string?

Pipe A, which is 1.20 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 = 0 at the closed end.
(a) How many nodes...

Pipe A, which is 1.50 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 = 0 at the closed end.

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?

A stove is connected to a stove pipe 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...
