    Calculating Phase Difference and Zero Point of Two Sinusoidal Waves

    Homework Statement Two sinusoidal waves in a string are defined by the functions y1 = (2.00 cm) sin(20.0x – 32.0t) and y2 = (2.00 cm) sin(25.0x – 40.0t) where y and x are in centimeters and t is in seconds. (a) What is the phase difference between these two waves at the point x...
