A string is stretched to a tension of 100 N, and has a linear density of 0.025 kg/m. An input disturbance causing a sinusoidal wave has a frequency of 150 Hz, with an amplitude of 5 cm.
Determine the speed of the wave.
Determine the wavelength.
Write down the equation describing the displacement of the string as a function of
the position and time.
a)
v^2 = T/u = 100 / 0.025
v = 63.246 m/s
B)
L = v / f = 63.246 / 150 = 0.4216 m
C)
x = A cos ( wt)
x = 5 cos ( 2 pi * 150 t)
x = 5 cos ( 942 t)

The tension in a string is 13.8 N, and its linear density is 1.05 kg/m. A wave on the string travels toward the -x direction; it has an amplitude of 3.17 cm and a frequency of 11.7 Hz. What are the (a) speed and (b) wavelength (in terms of m) of the wave? (c) Write down a mathematical expression (like Equation 16.3 or 16.4) for the wave, substituting numbers for the variables A, f, and λ.
