Question
Two sinusoidal waves in a string are defined by the wave functions
Y1 = 2.10 sin (15.0x - 34.0t)
Y22.10 sin (30.0x - 41.0t)
where x, y₁, and y2 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? (Your answer
should be between 0° and 360°.)
255
(b) What is the positive x value closest to the origin for which the two phases differ by ± at t = 2.00 s? (At that
location, the two waves add to zero.)
