Two wave generators S_{1}and S_{2}produce water waves of wavelength 0.5 m. A detector X is placed on the water surface 3 m from S_{1}and 2 m from S_{2}as shown in the diagram. Each generator produced a wave of amplitude A at X when operated alone. The generator are operating together and producing waves which have a constant phase difference of [tex]\pi[/tex] radians. What is the resultant amplitude at X?

a. 0

b. A/2

c. A/3

d. A

e. 2 A

2. Relevant equations

3. The attempt at a solution

Phase difference [tex]\pi[/tex] means that the two waves are completely out of phase.

The path difference (p) between the two sources = 1 m = 2 [tex]\lambda[/tex]. If p = n[tex]\lambda[/tex], it should produce constructive interference, but I think we have to consider the phase difference...

Now I'm confused how to relate these two informations to obtain the answer. Thanks
