The Double Slit Experiment: Part 4 of 8

This probably a dumb question, but what causes the particles to move toward a slit when they are directed at the centre?

[popparodz54]

There are no dumb questions in QM. For electrons, it is the "electron gun" at the back of your old-fashioned TV/computer monitor. I don't know how it works, find an engineer. For photons, it is a flashlight, or the laser equivalent, together with the fact that a photon can't stand still. For buckyballs, viruses, etc., IDK, a catapult should do fine.

i thought that small balls were photons, isn't a particle a physical thing?

[popparodz54]

later segments address the question of what it means to be a "physical thing." the balls of the illustrations may represent any quantum unit from photons to electrons to molecules and more.

add on for young's double slit experiment like you've never seen before

And this is a side comment, is it just me or is this a good looking white boy, just wondering. lol

@RandomResponse Yeah um, the distance angels travel in a day, and are made of light is in the Holy Quran, and the speed of light is that distance in a day down to all decimal points. Looks like God knew the speed of light before people did, oh but science and religion don't go together I forgot. Also the atomic weight of about 15 elements are in the Holy Quran, not the light ones, the HUGE ONES, wonder how they knew that over a thousand years ago. Dark matter, black holes, all sorts of stuff.

It has something to do with the way our mind registers the information. Our brain perceives it in the way that makes it look like it is trying to choose. My theory.

[azzy314159]

None of them seem to mention that the distance between the slits is of the order of the wave length of light. Examined as a wave the photon is doing nothing surprising.

[rginter123]

The truly weird part is if you use something to detect wich hole it goes through it stops making that wave patern

@popparodz54 not molecules lol

[RandomResponse]

@chrisofnottingham I agree

[RandomResponse]

@LBpDC That def looks like an altar behind him. Good for that religious university for actually accepting science
