Rayleigh Criterion FE
Канада
Добавлен 6 янв 2008
• Diffraction limits resolution.
• For a circular aperture, lens, or mirror, the Rayleigh criterion states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other.
• This occurs for two point objects separated by the angle θ = 1.22 λ / D, where λ is the wavelength of light (or other electromagnetic radiation) and D is the diameter of the aperture, lens, mirror, etc. This equation also gives the angular spreading of a source of light having a diameter D.
From hyperphysics.phy-astr.gsu.edu/hbase/phyopt/Raylei.html
Average vision is 5 × 10⁻⁴ radians or 103.13 arcseconds or a ratio of 1:2000 [1 unit resolvable at 2000 units]

Anyone can record this using any decent smartphone, no fancy Nikon Coolpix P1000 or P950 needed. Light is diffracted as it passes through an aperture, this is magnified when the camera is placed near a reflective surface. www.olympus-lifescience.com/en/microscope-resource/primer/lightandcolor/diffraction/

Anyone can make this observation, all that is needed is a camera and 500 to 600 meters of straight, flat and level track. Proximity to the rail surface dictates what can be seen. Camera jib is optional but if you have one, then use it to make the transition from top of rail to higher up smoother.

Look at all that REFRACTION....wow, LOLOL! JK! I didn't realize how USELESS this claim of refraction is. It avoids identifying what is observed as mirages, because all of them INVERT the visual, so it cannot be such a refraction called a mirage. But there are inversions of JUST the water area next to the subject. But get this!! Refraction ALSO includes the atmospheric warping of what you are seeing. Like at 2:44 seconds you see the platform with birds on it..The little warping you see happening due to the air is ALSO considered Refraction. SO the claim of refraction is MEANINGLESS. Then the one that is left is the ever so BS, the phenomenon, also disproven by time-lapse footage of day through night, or subjects with a directional light and not ambient light, as well as gps location.
Flerfs discovering refraction. How ironic.
The missing bottom of CN Tower and other buildings, prove the curvature without a shadow of a doubt. We live on a globe 🌍
Quality footage 👍
The Earth is flat.This is atmospheric refraction.
Isn’t it? What’s obstructing the ship then? If not curvature?
I wonder how in your videos Roger centre was there across lake Ontario🤔 I don't believe flat earth but I Wonder how rogers centre was there
I wonder what it would be like if you could see Cleveland from Canada like this🤔
And if you could also see Cedar point as a mirage from Canada
Nice view btw
Who was that man that said "what the hell"
Great video it proves that aeroplanes do not take a curved trajectory when they're flying over the Earth no curvature at all otherwise the liquid would've spilt . 👍🏾👍🏾👍🏾
Hilarious begging the question fallacy.
Terrible idea. Install it correctly.
HaHaHa, I have seen this a few times and love it. Thanks
So, not the Strutt Criterion??

What proof that the ground here is actually flat ? What about the obvious refraction of the rails ? This has been attempted once but it just displayed the ground actually wasnt flat.
If you want this channel about railroad maintenance ruclips.net/user/ccrx6700 you will learn that railroads spend time and effort to make railroad tracks as level as possible to reduce wear and tear on the rail and the trains and cars riding on them. The section of railroad I used is actually slightly elevated at the far end, perhaps 1 foot or so. Which further reduces any chance of curvature drop occurring here. There is no real refraction here, the optical phenomenon is actually diffraction, the light rays are colliding and interfering with each other. This was not an observation of flatness, this was an observation that diffraction causes, in this case an entire person to disappear and meld into the scene. So what can happen over short distance close to a surface can also happen at greater distances with the observing point next to a surface, especially one with a high reflective index, like water.
@@RayleighCriterionheated metal rails warms the air above causing light to go through different densities of air, distorting the image and the real position of the man. That is refraction, don't know why you would try to deny that. Also I won't take your word about elevation.

It's nice to see other FE'ers doing these types of observations. Unfortunately YT is IMHO not only censoring us but they don't put out notifications to all of our subscribers. I've been losing my interest in doing observation because I'm not getting half the views I used to. Hey they openly admitted to congress of how they would censor us but my question to them is why censor us if FE is so easily debunked. It's pretty discouraging but I guess that is their goal.
This joke is even more funny when you play Old World Blues in New Vegas.
Look up those buildings, where's the bottom? It obscured by the water curved. Compare it with a view from a sightseeing boat viewing Toronto City, you will see the bottom not visible in this clip
A limited angle will do that
@@siman6488 It even prove curvature, on the surface you can't see the buildings bottom, but if you raise your elevation higher then you will see the rest
@@phatsmall2007 incorrect, the distance would make the bottom unresolvable. The limited angle is to small to the bottom of the towers to resolve.
@@siman6488 Nope..You can watch here on RUclips there are several other Chicago skyline clips from 23 miles, 36 miles and 50+ miles, and the building getting even lower obscured by the water from the farthest distance. Definitely due to curvature, not about angle
It is not curvature, it is an optical illusion caused by Angular Resolution, Inverse Square Law and the Law of Reflections. My railroad videos have shown that curvature is not needed to make objects disappear. Because the tiny surface area of the bottom of the buildings are several magnitudes less reflective than tens of miles of water surface.
aww no window seat lol best you can do in that situation !
Imagine my chagrin when I saw short people sitting in the exit aisle seats, seats that tall people like myself need. The views out the windows wasn't that great anyway, too much cloud cover that was just blinding from the bright sun.
Am I thick...what am I looking at?
Just a bit of Physics regarding the Diffraction of Light www.olympus-lifescience.com/en/microscope-resource/primer/lightandcolor/diffraction/
Hey
I guess you mean refraction? Light bent by air of varying density due to temperature gradient over the rails. I was listening for a diffraction grating effect (caused by the sleepers)on the sound and couldn't hear it.
This is diffraction caused by light bending through the small opening of the camera www.olympus-lifescience.com/en/microscope-resource/primer/lightandcolor/diffraction/
@@RayleighCriterionI am still thinking it looks rather like a mirage, formed by the temperature gradient in the air above the rails. The light is not diffracting around a corner, through a slit or a diffraction grating.
I have a video like this with my camera just inches off the tracks. There are two visible bridges, one at one mile and the second at two miles. The tracks are always distorted and twisted before the first bridge.
Cmon, HIT THOSE 👍 FONZARELLIS
I just seen this the other night while watching Fallout.
No way!! What are the odds!!!!
Ooof, I only made it to S1E3. Is it even worth watching?
Yes, the story picks up and gets better after episode 4. I found it enjoyable to watch.
ohhh yes, but if you've already seen 3 episodes and are now asking something like that, you're not worth watching this masterpiece
@@robz537It's not a masterpiece, not even close but that doesn't mean it's bad either nor is it good. It's like the 1st season of The Witcher enough to make you want more seasons, mostly because of the lack of satisfaction with how it ended cause i have more questions than answers than I've first started watching and some forced writing, a good example is how the main characters meet each other. All i can say in favour of the tv show is that it's better than Fallout 4's main story. This shows a solid 6 or 7 out of 10. Hope they improve if not it's gonna be another Witcher.
If you don’t like it after 3 episodes you probably aren’t gonna like it at all.
No, it's f qing shi. If you believe in human dignity and all that is good, do not watch this. You might die.
Clouds of course. So the detail would be lost.
Where were you located?
My backyard, which isn't too far from the boarder. I had planned to go further south towards Buffalo to be closer to the totality, but the cloud cover there was not cooperating.
Clearly a flat plane, Clearly
I can use any desk globe and a tape measure to tell you any distance between any two points on earth and it will match reality, every time for every distance. Be a love and let me know which scaled flat world map I can use to achieve this same basic function. Ta muchly.

For more than 5 years, My wife and I have been going to the Humphrey Brook trail to walk. If it's not icy or really wet I like to walk a side trail that goes out to railway tracks. From the tracks, looking east, there is a bridge at one mile away, and a second bridge visible at two miles away. I can't tell you how many time I have climbed up there, but the tracks are always distorted, and warped out of sight before the first bridge, at one mile away.
I just had the cable come off the winding pulley. Would this set up help prevent that from happening?
It couldn't hurt as the previous setup was really pulling on the cable the wrong way, enough to cause one of the cables to begin fraying but no further fraying has happened since the newer setup.
Great example of flatwits drawing poor conclusions from their limited knowledge.
Ships should disapear after 50m? Dont get it?
Notice the tracks appear to curve like the Lake Pontchartrain hoax, distortion. Even though the tracks are straight.
Its going behind the trees lol
