Answer 2

Answer:

If you want light waves to continuously cancel, you have to get them moving together in the same direction and out of phase. This can be done with a single source and an interferometer

Explanation:

The two rays will quickly pass through each other, as if neither encountered anything, proving that photons are bosons. For the very very brief time that they occupied the same space, they would alternately experience constructive and destructive interference in the same way that waves sent from opposite ends of a long spring or rope do. These waves also pass one another with no lasting effect.
