The speed of light can be altered, who cares

You do. Crank up the intensity.

[Anonymous No.6027679]

But you do get the blurred out version from a single slit. Time to get gud at observing.

[Anonymous No.6027695]

>>6027679
yes you get it. effect is depending on the slit width and the distance to the screen. but there also is a physics class experiment showing this

[Anonymous No.6027718]

>>6027665

Care to explain, anon?

[Anonymous No.6027818]

Let's start at the typical starting place, the wikipedia article:
>In the basic version of this experiment, a coherent light source such as a laser beam illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.

Note: "a coherent light source such as a laser beam"

This matters. So does the width and spacing of the slits. It's not an easy experiment to set up based on the usual vague description.

Here are some people doing it with sunlight. You can see that it's not a straightforward interference pattern, as it would be with pure light of one frequency, but a continuum of overlaid interference patterns:

Also, as the guy points out, it's "so fiddly" that he had never before seen it done with sunlight. You need to get everything right to get it working.

What am I looking at here and why does it matter?

[Anonymous No.6029603]

>>6029602

Nevermind, figured it out.

I like David LaPoint's explanation for what he thinks photons are and why they have the wave/particle duality.

[Anonymous No.6029606]

>>6029603

Dude basically believes the unifying force of nature, or whatever, naturally pulls objects into bowl-shaped fields, so the smallest and largest objects we'll see in our universe take this shape, while everything inbetween is supported by these fields which allow for the variety we see.

[Anonymous No.6029607]

>>6029606

The wavelengths of light we see are merely the size of these fields.

[Anonymous No.6029608]

>>6029607

How these wave forms are compressed as they pass through a prism leads to refraction.

[Anonymous No.6029612]

>>6029608

How these fields are compressed as they pass along the edge of the slit leads to edge diffraction. The patterns we see in the double slit experiments is the result of these field reconnecting with itself through the other slit as the photon passes through its slit.

[Anonymous No.6029618]

>>6029612

A range of photons leads to a range of diffraction, and an interference pattern emerges with constructive and destructive interference.

Again, sounds like a good theory to me but I'm not schooled on optics so whatever.

[Anonymous No.6029633]

>>6029606
>>6029603

Oh yeah, and as far as the photon itself goes, he believes it is a point at the middle which shines brightly, caught between the two bowl-shaped fields not unlike plasma discharge experiments in the lab.

Pic on the right related.

you get the peaks with the single slit too. we saw it in high school physics class. just google single slit diffraction or something.

Primer fields anyone?

[Anonymous No.6030397]

>>6030078
this man knows. primer fields are nonsense.

[Anonymous No.6030416]

>>6030397
Well, I was reviewing all the math involve. And it works, just as classical mechanism limitations for some situations; primer fields explains and predict electrodynamics easily.
