1. ### Why the photon is disturbed by a hole?

I've already described this, but I'll say it again with more and slightly different words. (I recommend you reread what I have posted already) Assume the blocking material is an infinitely thin perfect absorber with a perfect hole and a perfect boundary, and assume the particle has 0...
2. ### Why the photon is disturbed by a hole?

There is no final path. Period. End of story. There is no model of why it ended up at a point. Only a probability for each point that can easily be calculated. There is no way to determine where it will go or, afterwards, how or why it got there. The waves or infinite paths are not...
3. ### Why the photon is disturbed by a hole?

" That is where you are missing the point. There is no single "final" path. There is only the sum of all the paths which sum to a probability amplitude for a given target location. If you only considered a "final" path you would see no amplitude variation. Think about it this way: In order...
4. ### Why the photon is disturbed by a hole?

The path blocking is just that -- a total blockage of the path. A perfect absorber. Either the path is allowed, or it is totally blocked. To the extent that the particle is affected by the blocking barrier in some other way, it is noise (it actually becomes entangled with the barrier) and...
5. ### Why the photon is disturbed by a hole?

You seem to be struggling with the concept of a particle being affected by the material near its path to cause it to take a curved path and cause diffraction. But you can't think of it that way. If you want to understand diffraction in terms of particles you need to think in terms of feynmans...
6. ### Two convex lenses in a system?

Google "2 convex lenses" and look at the images that come up. If you then have questions, please post them.
7. ### 1 question about light

I have a perfectly clear photograph of Half Dome from Lick Observatory, and it is 120 miles away (and you can see the mountains beyond). I have seen it naked eye when flying into San Jose airport, and could see much further...
8. ### 1 question about light

He wasn't being all that literal about across the atlantic. In my opinion was interested in the effects of light through the atmosphere over a long distance and light propagation. I mentioned the curvature, but didn't consider it pertinent to the issues he was confused about. I also suggested...
9. ### 1 question about light

There is nothing about the light rays or their radiation from the target object that limits the distance (as you inferred in the original post). They don't separate as the light travels. Are you clear on that? Light won't bend significantly due to the Earth's mass. You can read and...
10. ### 1 question about light

The light rays from a point source disperse as you described. The light rays from your body that are reflected directly toward the receiver do not further disperse in that same way. Not all the light from the projector is reflected directly toward you or he would be a mirror. If you were...
11. ### If a light goes from space to a glass

The frequency of light does not change in different mediums. The wavelength changes because the speed of light though the media changes. But, to take the point 1 furthur, you cannot see the light in glass. You can only see light that enters your eye, in which case it is no longer in glass.
12. ### Passive long range sensor using radio wave distortions?

Trying to re-invent the metal detector? I'm really not clear about your description and what you are trying to accomplish at the top level that is different than a metal detector. I don't think waves distort other waves. I think that is what you are expecting. You can get interference...
