If two sound sources (A, B) are placed in a water tank and emit sound waves at the same frequency, phase and amplitude, if I measure the sound intensity at point A, will the detected signal will be ~double than the emitted signal of each sound source?
I think that the answer is yes because of the constructive interference between the sound sources, but what is not clear to me is why- all the sound waves that are emitted from source A have momentum in the direction of point B, if the net movement of the water molecules is in the direction of point B, how do they interact with a detector at point A (they only move away from it..)
