Standing Wave

  1. May 12, 2010 #1
    1. The problem statement, all variables and given/known data

    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 = 5.00 cm at t = 2.00 s?
    (b) What is the positive x value closest to the origin for which the two phases differ by at t = 2.00 s? (This is where the two waves add to zero.)

    2. Relevant equations

    What do you call the phase of a sinusoidal wave?
