Hello!
Here is something though that has been haunting me recently. If lights from two different sources meet and the distance that the lights have traveled from each source differs a half of the wave length of the one photon the light waves will “destroy” each other and if they meet on a screen then it should be impossible to see any light spot at all. That is what we call interference. So much is clear. Here is the part that bothers me.
If light waves are anything like water waves then they really can’t be destroyed in the sense that they stop to spread or permanently stop their movement, the rather “stop” to exist at that particular spot they meet the other wave and interact with it. But they continue their movement just like nothing ever happened after that spot.
So if we look at it that way, the light waves still should reflect against the screen the hit even if they both get “neutralised” and destroyed by each other right? So why is it that we can't see them any more? And they no longer can provide the eye any picture of the surface they have been reflected from? Or do they get completely destroyed (don’t travel anymore) after they have meet each other? And if so, why is my water wave theory wrong?
Thanks a lot everyone for your contribution
