A guitar string with a linear density of 2.0 g/m is
stretched between supports that are 60 cm apart. The string is
observed to form a standing wave with three antinodes when driven
at a frequency of 420 Hz. What are (a) the frequency of the fifth
harmonic of this string and (b) the tension in the string?

A stretched string has a mass per unit length of 5.00 g/cm
and a tension of 10.0 N. A sinusoidal wave on this string has
an
amplitude of 0.12 mm and a frequency of 100 Hz and is
travel-
ing in the negative direction of an
x
axis. What are the (a)
speed, (b) wavelength, and (c) period of the wave?

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 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)
