How can light interfere with other light? I thought EM radiation only interacts with charges?
Is it because, at your eye, the EM waves are out of phase? So the EM waves don't 'delete' each other, they both exist in superposition with each other, and one EM wave is pushing the electron one way, and the other pushing the other way, so the net effect is 0?
