Question

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 z , corresponding to a rise in pitch from C to D? What is U, the mass per unit length of the string? To determine the wave speed from purely kinematic quantities, you need to know the wavelength of the wave. What is the wavelength λ λ of the fundamental mode in the C string of the cello?.

Answer #1

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 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)

A typical steel B-string in a guitar resonates in its
fundamental frequency at 240 Hz. The length of the string is 0.600
m. What is the wave velocity in the string?
The tension in the above string is 81.2 N. Calculate the mass of
a 4 m long piece of the steel string.
What is the wavelength of the third harmonic of the guitar
string described above?

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?

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...

Consider an oscillating string in which the wavelength of the
fifth mode is λ meter. 5 = 6 a) Fill in the blank. Each end of the
oscillating string is a ____. b) Draw the string oscillating in its
fifth mode. c) From your diagram, how many wavelengths of this
fifth mode fit into the unknown length, L, of the oscillating
string? d) Since the wavelength of the fifth mode is given as equal
6 meters, what must be the...

1. In an experiment to study standing waves, you use a string
whose mass per length is µ = (1.8 ± 0.1) × 10−3kg/m. You look at
the fundamental mode, whose frequency f is related to the length L
and tension T of the string by the following equation L = 1 2f s T
µ .
You make a plot with L on the y-axis and √ T on the x-axis, and
find that the best fitting line is...
