11) A wave traveling on a string has the following wave function, y(x, t) = Asin(kx + wt + 9). At time t = 0, the point x = 0 has a displacement of y(0,0) = 0, and is moving in the negative y-direction. Which of the following is true about the phase constant and the wave speed direction? (a) g = "/2, and the wave is moving in the negative x -direction. (b) = "/2, and the wave is moving in the positive x -direction. (c) 9 = n and the wave is moving in the negative x -direction. (d)ø = n and the wave is moving in the positive x -direction.
