A wave traveling on a string has the following wave function, y(x,t) = Asin(kx + ωt + φ). 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)φ = π/2, and the wave is moving in the negative x −direction. (b)φ = π/2 , and the wave is moving in the positive x −direction. (c) φ = π and the wave is moving in the negative x −direction. (d)φ = π and the wave is moving in the positive x −direction.
