You have a piece of string with a length of 4.0 m and a total
mass of 0.200 kg. You stretch the
string between two supports with a tension of 5.0 N. You then
excite a traveling wave by shaking
the left end of the string up and down so that:
y(x = 0, t) = (1.0 cm) cos(2π(1.0 Hz)t)
a) What are the wave speed, frequency, wavelength, angular
frequency and wavenumber of the
resulting sinusoidal traveling wave?
b) What is the amplitude of the wave? What is the energy per
wavelength in the wave? c) Sketch
the wave at t = 0, t = 0.25 s, t = 0.50 s, and t = 0.75 s.
