Question

A Piano that has a string of L = 2(m) long and a mass of m = 0.2(g) over that length. The Piano is tightened and its tension is T = 20(N). Determine the speed of propagation for a wave along that string? Let the fundamental mode has a wavelength of λ = L 2 Determine the frequency of sound associated with that string?

Answer #1

To apply Problem-Solving Strategy 12.1 Standing waves and normal
modes. A cellist tunes the C string of her instrument to a
fundamental frequency of 65.4 Hz H z . The vibrating portion of the
string is 0.600 m m long and has a mass of 14.4 g g . With what
tension must she stretch that portion of the string? What
percentage increase in tension is needed to increase the frequency
from 65.4 Hz H z to 73.4 Hz H...

7. One string of a certain musical instrument is 80 cm long and
has mass of 8,72 gram. It is being played in a room where the speed
of sound is 344 m/s.
a. To what tension must you adjust the string so that, when
vibrating in its second overtone, it produces sound of wavelength
3,40 cm?
b. What frequency sound does this string produce in its
fundamental mode of vibration?
PLEASE ANSWER CLEARLY

A particular guitar string has a mass of 3.0 grams and a length
of 0.75 m. when it is stretched, it produces a transverse wave of
frequency 1200 Hz and wavelength 2/3 of the length of the string.
(i) What is the speed of the transverse wave on the string? (ii)
What is the tension of the string?

A violin string of length 40 cm and mass 1.4 g has a frequency
of 526 Hz when it is vibrating in its fundamental mode. (a) What is
the wavelength of the standing wave on the string? (b) What is the
tension in the string? (c) Where should you place your finger to
increase the frequency to 676 Hz?cm from the fixed end of the
string (from the peg of the violin)

Standing waves on a 1.5-meter long string that is fixed at both
ends are seen at successive (that is, modes m and m + 1)
frequencies of 38 Hz and 42 Hz respectively. The tension in the
string is 720 N.
What is the fundamental frequency of the standing wave? Hint:
recall that every harmonic frequency of a standing wave is a
multiple of the fundamental frequency.
What is the speed of the wave in the string?
What is the...

A guitar string has a linear mass density of 0.005 kg/m, a
tension of 100 N, and is supposed to have a fundamental frequency
of 110 Hz. When a tuning fork of that frequency is sounded while
the string is plucked, a beat frequency of 2 Hz is heard. The peg
holding the string is tightened, increasing the tension, and the
beat frequency increases.
Before it was tightened and while it still had
a tension of 100 N, The frequency...

A standing wave is set up in a L=2.00m long string fixed at both
ends. The string vibrates in its 5th harmonic when driven by a
frequency f=120Hz source. The mass of the string is m=3.5grams.
Recall that 1kg = 1000grams.
A. Find the linear mass density of the string
B. What is the wavelength of the standing wave
C. What is the wave speed
D. What is the tension in the string
E. what is the first harmonic frequency...

A stretched string is 1.91 m long and has a mass of 20.9 g. When
the string oscillates at 440 Hz , which is the frequency of the
standard A pitch, transverse waves with a wavelength of 16.7 cm
travel along the string. Calculate the tension ? in the string.

A rod 2 m long, 2 cm in diameter and 5 kg in mass is fixed at
one end and is stricken by a force F to produce a 3rd overtone and
elongates at 1 cm. A string of length L and mass 750 grams is puled
by a T = 30 to produce a 3rd harmonic frequency. Determine the
force F and length L that produces the same value of frequencies in
the two materials, if the sound wave...

A guitar string of length 72.8 cm (which might be out of tune)
has been plucked and is producing a note of frequency 334 Hz. (a)
What is the speed of transverse traveling waves on this guitar
string? Give your answer in m/s. HINT: The note you hear is
produced by the vibrational mode of the string which has the
fundamental (lowest possible) frequency. Draw a picture of the
string vibrating in that mode and determine the wavelength of the...
