1. The problem statement, all variables and given/known data One speaker is located at the origin and the other is located at (x,y)=(0,3.00m). The speakers emit identical sound waves of wavelength 2.00m which are initially in phase. Where does constructive interference occur? ANS: x=1.50m 3. The attempt at a solution Difference of the distance of the two speakers = λ = 2 √(3^2 + d^2) - d = 2 (3^2 + d^2) = (2 + d)^2 9 + d^2 = 4 + 4d + d^2 5 = 4d d = 1.25m What's wrong with my attempt, please?
