A 2.00-m-long rope has a mass of 0.100 kg. The ten-
40
sion is 60.0 N. An oscillator at one end sends a harmonic wave
with an amplitude of 1.00 cm down the rope. The other end of
the rope is terminated so all of the energy of the wave is
absorbed and none is reflected. What is the frequency of the
oscillator if the power transmitted is 100 W?
A taut rope is tied to a machine that causes it to
oscillate sinusoidally. You take a picture of the
rope and see that at that moment there are four
complete cycles along 10m. If the oscillator
frequency is 20HZ, find:
a) The wave number
b) The angular frequency
c) If at time t = Os, the height of the wave is Om
when x = 0m, find the phase shift of the
oscillation.
d) If at time t = Os, the transverse velocity is 250m
/ s when x = Om, find the amplitude of the
oscillation.
e) Write the wave function that describes the
behavior of this wave.
