Photon dynamics in the double-slit experiment

[EGarrett01]

Is it possible that the photon could bounce off the edge of the slit, so to speak, in order to hit the middle of the paper?

[husooo92]

The diffraction patterns occur because of the wave properties of photons. However when you try to observe what happens to the photon before it goes through the slit, it behaves like a particle (like the tennis ball example). So when we try to observe it before the slits to see what happens, the photon only goes through one of the slits each time to generate two 'smudges', but when we dont look it goes through both of the slits.

[jsound42]

I think we're not seeing the whole picture.

I think that the photons are not actually in 2 places at once, but what we are seeing is the effect of the photons as particles of a wave that fluctuates throughout the 11 dimensions. That's why the resulting pattern appears wave like even if we're only "seeing" certain parts of it. It's almost as if the photons don't care that there is a barrier is there because in some dimensions, it's not.

I don't see how a photon would know when to split and WHERE to go ? What if the 2 slit wall were closer to the gun or what if the wall was closer or further away etc. I would conclude that the photons move through either slit, but not split into two then merge again..

Then again I aint no physicist, just my $0.02

[montzigner]

lol... "whats a photon?" "well its... uh.. its... its kind of like... sort of..." "you dont know what a photon is, do you?"

[Trajedya84]

ok just an observation, i have noticed the center has a brighter spot i think there are 2 different particles involved there one that hit the center is a different particle that hit the from the sides. Could it be that a single photon release an extra particle?

no, ill tell u why it happens. photon bounces from the edge of a slit. watching "trough eyes of a photon" on the edge of a slit theres a whole new surphace (4 exactly, 2 by 2 watching each other) that bounce photon same angle back till it reaches and hits surphace that has bigger angle. why is so dificult to understand that photons bounce of surphaces???

[vehicar]

except that the maximum angle that the photon would hit the detector at in your scenario is much less than the angle that the photon would have to hit the detector at to be spaced that way. in addition, if the effect was that the photons bounced off of the material, the distribution would be a wide bar in the middle, like this: () , instead of the actual result, like this: | | ||()()|| |

[cauda123]

just like in single narrowing slit experiment u mean - that has "unexpainable" results. well, it would be the way you said if ud "shoot" mass of photons trough slit narrower than the ray, but thats not case here. so its more logic than misticism

[buckamoona]

but doesn't light bend to gravity? what if it just bends and hits the middle?

[supremekingof]

yes light bends to gravity, but on earth the gravitational force is the same, there arent areas with more gravity than others, gravity is a constant; there for there is no gravity acting on the photons at one point that is not at another point.

[AHARG1974]

gravity is not a constant in all places.

[9hello123]

@supremekingof There is differences in gravity all over the world. If you walk a single step there is a difference in gravity.

[gatzkeRob]

I think I disagree with this. The object with the two slits has a thickness and I think the particles are bouncing off the walls of the slits.. I think their results would vary a great deal if the slitted object varied in thickness..

[supremekingof]

incorrect, then you would see the same phenomena from a single slit experiment which you do not. With a single slit still smaller then the beam of photons, there is only one line created. By your idea, the thickness of the slit would still produce multiple lines at various angles, but it does not.

mark everett, weird physics and annie mac?

i think im in heaven haha

[y2knoproblem]

What if the photons were ricocheting off the insides of the slits?

[user134342]

good question that shows thinking. But wouldn't the regular particles also do the same?

[jonathonfrum]

If they're banging off the slits, why the perfect interference pattern? Interference is the only explanation.

[supremekingof]

exactly, but most people here dont understand what an interference pattern is. The photons show a phenomena closer to waves than to matter, and a wave can hit multiple places, matter should not be able to, but in the double slit experiment it matter somehow does.

[thisdude2020]

omg wow this accually amazes me. I was super sketchy when seeing it done by computer animation but now that i see a real live thing!! omg that is soo cool and creepy. This accually changes my perception on reality. What seems real isnt always real...scary

[clemzzz]

what's the music going on , it's great

[zeeleekiwi]

it's all music by Eels

The guy being taught is Mark Everett, the Eels front man.

[sn1pe352]

It takes a touch of genius -- and a lot of courage to "dumb" down physics and q physics so people like myself can understand

Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius -- and a lot of courage -- to move in the opposite

[imboblolgodie]

well said

[Chronosaur]

Pretty awesome that the guy from eels is Hugh Everett's son. Is it just me, or does the narrator have a really sexy voice?

[rixplrer]

excellent, ive seen recreations by computers of this experiment many many times but never seen a real one going on. very very nice

[imboblolgodie]

yh its more believable when real ppl do it...not doctor quantum...ive seen it irst hand in my school...and its scary to think how this undermines all we believe to be ''certain..the one thing this shows is certain is that nothing is certain but our certainty that nothing is certain ^^

[oni8245]

lol wow this was just added...weired.....but isnt it actuly the interferance wave thingy?
