1.A harmonic wave on a rope is described by the expression
y(x,t)=(4.3 mm)sin[ (2pi/0.82 m)(x+ (12 m/s)t) ]
What are the wave’s wavelength, period, wave number, frequency, and direction of
2.For the wave in qus 1 above, determine the displacement and acceleration of the
element of the rope located at x = 0.58m at the instant t = 0.41s.
