A sinusoidal transverse wave of wavelength 24.0 cm travels along a string in the positive direction of an x axis. The displacement y of the string particle at x = 0 is given in the figure as a function of time t. The scale of the vertical axis is set by ys = 3.00 cm. The wave equation is to be in the form of %3D y = Ym sin(kx - wt + p). (a) At t = 0, is a plot of y versus x in the shape of a positive sine function or a negative sine function? What are (b) ym, (c) k, (d) w, (e) ¤, (f) the sign in front of w, and (g) the wave speed (speed of the wave along the string) and (h) What is the transverse velocity of the particle at x = 0 when t = 4.00 s? y (cm) Ys 10
