Question

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 traveling waves which combine to produce the standing wave that you have drawn. m/s (b) In the sound wave that is traveling from the guitar string to your ears, what is the distance between adjacent condensations? (For the speed of sound in air use the value, at 20 degrees Celsius, from the inside front cover of your textbook.) m

Answer #1

a. A guitar string is vibrating with a wave having a wavelength
of 1.6 m. This string has a linear mass density of 20 g/m. If the
tension holding the string is 7500 N, what is the frequency pitch
of the sound produced? Answer in 2 decimal places, and units
assumed in Hz.
b. Echolocation is a technique used by some animals such as
bats, whales and dolphins to assess their surroundings without
using vision. A whale gets too far...

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 string with both ends held fixed is vibrating in its third
harmonic. The waves have a speed of 193 m/s and a frequency of 235
Hz. The amplitude of the standing wave at an antinode is 0.380
cm.
a)Calculate the amplitude at point on the string a distance of
16.0 cm from the left-hand end of the string.
b)How much time does it take the string to go from its largest
upward displacement to its largest downward displacement at...

On a guitar, the lowest toned string is usually strung to the E
note, which produces sound at 82.4 Hz. The diameter of E guitar
strings is typically 0.0500 inches and the scale length between the
bridge and nut (the effective length of the string) is 25.5 inches.
Various musical acts tune their E strings down to produce a
\"heavier\" sound or to better fit the vocal range of the singer.
As a guitarist you want to detune the E...

A thin taut string of mass 5.00 g is fixed at both ends and
stretched such that it has two adjacent harmonics of 525 Hz and 630
Hz. The speed of a traveling wave on the string is 168 m/s.
(a) Determine which harmonic corresponds to the 630 Hz
frequency.
(b) Find the linear mass density of this string.
(c) Find the tension in the string.

A thin taut string of mass 5.00 g is fixed at both ends and

The overall length of a piccolo is 30.0 cm. The resonating air
column vibrates as in a pipe open at both ends. (a) Find the
frequency of the lowest note that a piccolo can play, assuming that
the speed of sound in air is 340 m/s. Hz (b) Opening holes in the
side effectively shortens the length of the resonant column. If the
highest note a piccolo can sound is 5000 Hz, find the distance
between adjacent antinodes for this...

A harmonic wave of amplitude 10.0 cm passes through a string.
The harmonic wave has a frequency of 37.5 Hz. What is the average

through the string? Give your answer in units of m/s, to three
significant figures.
