A history graph at x=1.5 m of a wave traveling in the negative x-direction at 3.2 m/s. a.) What is the wavelength of the wave? b.) Using the sine function to describe the wave, what is the intial phase constant of the wave if D(x=1.5, t=0) = 1.27 cm? c.) Write a complete expression (in terms of sine function) for the displacement of the string as a function of position x and t in SI units.
