@blitzphd: I was looking into making a video about caustics in pools and coffee cups, and then I stumbled upon a website describing rainbows that way! A few hours later and you have this video. #physics #rainbow #caustic #explained

Crowchet :

Drove through the "end" of a rainbow

Zeno :

You’ve yet to explain the leprechaun and pot of gold! Shame

ceejenj :

Nice lesson

hissss :

where do bad rainbows go? prism

c28h30o2 :

Doesn’t everyone see the rainbow in a different and unique way depending on perspective?

Jellybean :

It’s interesting! I never understand the mathematics part of it. However, most of the time I understand the theory part of it if that makes sense.

IApproveOfEnrichment :

so cool! does the rainbow also have infrared and UV bands?

Sasha :

If you pause the video here, you can be savagely reminded of how much math you've forgotten since high school / college 🥲

The_Rocket_Man :

So it’s not because of the firmament ?!?! 🤯

GoblinNinja :

What I’ve always wondered is with all the droplets of water in a cloud, spread out over x, y and z axis, how is the rainbow in one place? Is the rainbow coming from a single droplet? If not, how do they coordinate? Mystified. But still, this is very informative.

origumi :

you forgot to mention the leprechauns

wibbsrom :

when there’s a double rainbow, the colors go in the opposite direction- roygbiv on the bright one and vibgyor on the 2nd. Pretty cool!

Marko Samardzic :

if we stand next to each other, we see 2 diferent rainbows. that is fascinating to me. it's your own rainbow

5Up :

ty! I have always wondered about the white glow and never bothered to look into it

Shang-chi :

Is it the light bending Because of all the water?

matt :

real water droplets are pretty far from the perfect spheres as shown in the diagram, so does the specific shape of the droplet not really matter?

cldbrwszn :

How do double rainbows work?

sty'el levon :

Light is genuinely confusing. 🤦🏾‍♂️Why is there a spectrum of different colors and we only see a few with human eyes? And How does it get decided on what will be able to be seen by different creatures and beings? And how do scientists know which creature can see in other colors?

Rylan :

I have been trying to wrap my head around this for years, but it wasn't until this graphic that I finally got the explanation. this just is clear to me in ways that a lot of other graphics I've seen just aren't

Ed :

ok but why do some rays remain white and other turns into colors?

George :

The Coffee Elemental :

Do infrared and ultraviolet ‘bands’ exist in a rainbow?

Ethan's - philosophy journal :

well the other day I saw a supernumerary rainbow! it was like looking into a crazy rainbow tunnel. light and water is doing something extra for this!! 😂

[REDACTED :

low key your the reason I took physics
