How prisms work (video linked above shows why light 'slows down')

A link to the full video is at the bottom of the screen.

There, I wanted to dig deeper to understand light slows down, and why this would depend on the color.

But _why_ does light slow down, and why it would depend on frequency? This is what the full video linked at the bottom of the screen explores.

The intuition for why it depends on color comes down to what happens if you're bad a pushing a child on a swing. I promise that makes sense in context!

I love seeing examples of the Fourier transform pop up in places you wouldnt immediately expect

The way a prism works is you shine a light at it and a pink floyd song starts playing

[rogueangel]

So a prism’s basically an incredibly analogue fourier transform generator

you see colors from a prism, I hear "Any Colour You Like"

Hey this would make a great album cover

No one told you when to run, you missed the starting gun. - Joseph Fourier, 1790

Light goes in.

**pink floyd automatically starts playing in my head from seeing the prism**

This was originally discovered by two scientists named Roger Waters and David Gilmour.

[mcdeezyofficial]

someone should use that as an album cover

[MrFern]

That’s a way more in depth description than I got in high school

[robcarnaroli]

Dam you Fourier. You're everywhere!

It also includes frequencies we cant see. Infrared light was discovered by splitting light into a rainbow over a row of thermometers. The control happened to be next to the red and started rising rapidly.

I never knew that i dont know the concept of prism until this video

[Nic]

Thank you for shedding light -- on this.

This short blew my mind and led to me clicking the full video, and then immediately subscribing.

As a "sufficiently curious" empiricist, everything about your presentation approach was AMAZING.

So excited to watch my next video after leaving this comment.
