These two waves travel along the same string: y1(x, t) (4.60 mm) sin(2px 400pt) y2(x, t)
Chapter 16, Problem 37(choose chapter or problem)
These two waves travel along the same string: y1(x, t) (4.60 mm) sin(2px 400pt) y2(x, t) (5.60 mm) sin(2px 400pt 0.80p rad). What are (a) the amplitude and (b) the phase angle (relative to wave 1) of the resultant wave? (c) If a third wave of amplitude 5.00 mm is also to be sent along the string in the same direction as the first two waves, what should be its phase angle in order to maximize the amplitude of the new resultant wave?
