Q1. A transverse sinusoidal wave given by y (x, t)=ym sin (2.5x-440t+q) is traveling along a string (x and y are in meters and in seconds). At time t=0 s and at position x = 0 m, the wave has displacement y = +4.5 mm and transverse velocity u=-0.75 m/s. What is the phase constant of this wave? the answer is 69.3 degrees. please show your work and show how you found the amplitude if needed in the method.
