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 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 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...

A steel wire in a piano has a length of 0.5000 m and a mass of
4.200 10-3 kg. To what tension must this wire be stretched so that
the fundamental vibration corresponds to middle C (fC = 261.6 Hz on
the chromatic musical scale)?
--------
Two pieces of steel wire with identical cross sections have
lengths of L and 2L. The wires are each fixed at
both ends and stretched so that the tension in the longer wire is...
