When two waves cancel each other out, where does that energy go? I know that once the two waves separate again they no longer interfere and are normal waves again, but what if they hit an absorbing object as they are interfering? Is the energy hitting the object zero? I mean, the energy still has to be there somewhere, but if there's no light energy at the point of interference, where did the energy go?
Also, would it be possible to perfectly align two lasers of identical wavelengths so that they exactly cancel each other out?
