The Ultimate Simplification: Letting a 'Single Atom' Replace the Slits (Part 3)

To begin with, can light be fired as particles? (Part 2) is here💁‍♀️
🌟The ultimate double-slit experiment, explained for elementary school students!

1. To begin with, what is so mysterious about it?

Light has a mysterious rule.

• When it passes through secretly → 🌊 It acts like a wave

• When the path is revealed → ⚪ It acts like a particle

👉 It cannot be both at the same time

This is the most important part of the double-slit experiment.

2. Do the slits really have to be 'holes'?

Usually, you make
🕳️　🕳️
like this, two holes (slits) in a plate.

But you know, what this paper taught us is—

Surprisingly, even
atoms (incredibly tiny particles) can
act as slits‼️😳

3. What does it mean to use atoms as slits?

But if left alone, atoms...

🏃💨 Zip and zoom all over the place!

So the researchers came up with an idea.

🔦 With a laser,
❄️ cool them down tremendously!

Then the atoms...

🧊 Become still, as if trapped in ice

👉 30,000 atoms
👉 30,000 'slits made of invisible atomic particles'

We called this
the smallest slit that can be made
.

④ What if we shine light 'one particle at a time'?

Light, too, gently...

Pop
pop
pop...

💡 almost one by onewe hit the atom.

Then, something strange happens.

⑤ When the atom is 'fixed'

When the atom is firmly fixed and
not blurry...

📸 The path of the light
👉 can hardly be recorded

Then the light,

🌊🌊🌊
behaves like a wave, and striped patterns (interference fringes) appear

⑥ When the atom is 'hazy'

Now the opposite.

When the atom is
☁️ a little ambiguous about where it is
☁️ and is spread out hazily...

👣 When light passes
👉 footprints (information) are left behind

Then the light,

⚪⚪⚪
becomes like particles, and the stripes disappear

⑦ The most important conclusion!

This is the core of this paper.

❌ Whether it was observed → Irrelevant
❌ Human consciousness → Irrelevant
❌ Spring mechanism → Irrelevant

⭕ Whether information remained
⭕ Whether it was 'recorded' somewhere in the world

That is all.

In the current example,
🧊 We place a slit made of a pillar of 30,000 atoms trapped in ice, and fire light one photon at a time.

At this time, if one of the two pillars (which contain 30,000 atoms) moves slightly, information remains (= it is known which pillar it passed through), so the wave nature disappears and the light behaves as a particle.

On the other hand, if the two pillars do not move at all, no information remains, so the wave nature of the light is not lost, and interference fringes appear.
