A rope, under a tension of 294 N and fixed at both ends, oscillates in a second-harmonic standing wave pattern. The displacement of the rope is given by
y = (0.16 m) sin[(?x/4.0] sin[13 ?t]. where x = 0 at one end of the rope, x is in meters, and t is in seconds.
What are
(a) the length of the rope,
(b) the speed of the waves on the rope, and
(c) the mass of the rope?
(d) If the rope oscillates in a third-harmonic standing wave pattern, what will be the period of oscillation?
