I added a picture , please comment where I am wrong. As I understand it, if you shoot let's say a photon from A to B, it doesn't really travel in the traditional way. It travels as a probability wave, until it interacts with another photon or atom of a wavelength that is shorter then itself?
So as time goes on, the probability of finding that photon in a certain spot moves from A to B at the speed of light? The red area represents, this probability and how likely it is to detect the photon in that place. The horizontal line represents the distance and location. And T is different snapshots as time goes on. I drew 3 snapshots, let's assume it takes T=5 to reach it's location with the speed of light.
Im sure the probability wave looks all wrong, but just a simple visualization to get the concept right.
So my question(s),
1. Is it true that this probability wave moves at the speed of light (given that we are talking about a photon here) in a linear fashion from A to B. So not the actual particle, but the probability to find it.
2. But technically, it could move slower or faster? As in it is possible to detect it near A, even though it should almost have reached B judging by the speed of light? So there is a chance that if you turn on a detector near A after time T=4 (let;s say it takes T=5 to go from A to B if you assume light speed), there is a very small chance you could still detect it near A some of the time if you repeat the experiment many times? And as it is affected by this detector, it will then move the remaining distance to B in the classical sense as a particle at the speed of light? Thus technically traveling slower then the speed of light for the total distance between A and B?
3. Could you then say that the average speed of light is 300m m/s? As in if you don't interact with the photon in between A and B, you will always measure light speed. But if you measure it in between you will get different speeds between A and B, but averaging light speed in the end?
Or does this probability wave always travel exactly the speed of light? Or am i just babbling nonsense and have I got this completely wrong? Where do I go wrong?
Any feedback would be welcome
Thanks!
