Homework Help: Physics

Which of the following is correct for the two coherent light waves to produce zero light?

The light waves should travel in perpendicular directions.

The light waves are in phase with each other.

The light waves are out of phase with each other.

The light waves should pass through a prism.

I would think that the answer would be C (the light waves are out of phase with each other), but I feel like that may be one of those trick-questions.
