Two waves, both of amplitude A, are traveling in opposite directions along a rope. What is the range of displacement y that the two waves may cause when they overlap?
A. -2A ≤ y ≤ 2A
B. -A ≤ y ≤ A
C. -1/2A ≤ y ≤ 1/2A
D. 0 ≤ y ≤ A
(Honestly not sure how to solve this but I think the answer's A...)

you solve it by adding A sinTheta+AsinThetaA=2A SinTheta, which ranges from -2A t0 2A
Thank you. :)
