Water waves of wavelength 4m are produced by two generators S1 and S2.

Each generation when operated by itself produces waves which have an amplitude A and P which is 3m from S1 and 5m from S2.

When the generator are operated in phase, what is the amplitude of oscillation at P?

A. 0

B.1/2A

C. A

D.2A

»»answer is A. I just need the reasoning :)
