Question

A tube closed at one end has resonant frequencies that are 300 Hz apart. If this tube is now opened at both ends, what is the 1st harmonic frequency?

Please explain the n values in great detail used for the formulas (other Chegg answers do not do this).

What are the first 3 resonant frequencies on a 20cm long
tube, with one end closed? Use your speed of sound measurement in
this calculation.
Speed of sound measurement = 339.8 m/s

What frequencies (in Hz) will a 1.95 m long tube produce in the
audible range (20 Hz - 20,000 Hz) at 15.0°C for the following
cases?

What frequencies (in Hz) will a 1.55 m long tube produce in the
audible range (20 Hz - 20,000 Hz) at 21.0°C for the following
cases?

A tube which is open at one end and closed at the other end has
a length of 0.25 m. assume the speed of sound in the tube and in
the surrounding air 350 m/s.
a. Make one drawing of the tube for each of the three resonances
with the longest wavelengths possible for the tube (i.e. 3 drawings
total). Label the wavelength on each drawing (or a fraction of the
wavelength if a full wave is not present), the...

You have two air columns that are each 2.470 m long. One column
is open at both ends and the other is closed at one end. You wish
to determine the frequencies you can produce in the audible range
(20 Hz–20,000 Hz) on a day when the temperature of the air is at
24.00°C. (Give your answers to at least four significant figures.
Assume that the speed of sound at 0° C is exactly 331 m/s.)
(a) in the column...

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?

Find the fundamental frequency and the frequency of the first

A tube 1m long is closed at one end. A stretched wire is placed
near the open end. The wire is 0.30m long and has a mass of
0.010kg. It is held fixed at both ends and vibrates in its
fundamental mode. It sets the air column in the tube into vibration
at its fundamental frequency by resonance. Find (a) the frequency
of oscillation of the air column and (b) the tension in the
wire.

Lets say you want to make a tube, closed at one end, that has a
fundamental frequency of 262 hz. Lets assume that the speed of
sound is 343m/s and that the diameter of the tube is 4.0 cm. What
length would you cut the tube?

A pipe is 2.37 m long.
(a) Determine the frequencies of the first three harmonics if
the pipe is open at both ends. Take 344 m/s as the speed of sound
in air.
f1 = 72.6 Correct: Your answer is correct. Hz
f2 = 145.2 Correct: Your answer is correct. Hz
f3 = 217.8 Correct: Your answer is correct. Hz
(b) How many harmonic frequencies of this pipe lie in the
audible range, from 20 Hz to 20000 Hz?
275...
