Beautiful Science - Why does the sky change color at sunset?

Blue to red, why does this happen?

If you were to look up at the sky on a clear day, you will notice the sun is yellowish., (Don’t look directly at the sun peepz) and the sky blue. But as the sun lowers on the horizon, the colour of the sun and the sky can change dramatically to red, orange and yellow hues. But why does this happen?
The light from the sun is white, but actually consists of the seven coloured waves, red, orange, yellow, green, blue, indigo and violet. If we were to look at the sun from space it would always appear white, but on earth the atmosphere scatters some of the light waves coming from it. This is called Rayleigh scattering and affects what colour we perceive the sky and sun as.
The waves at the red end of the spectrum are longer and at the blue end shorter. This means blue waves are more likely to hit particles in the atmosphere and scatter, hence why during the day we see the sky as blue. The sun will appear yellowish as the combination of the colour wavelengths that make it through easier, like red and green that combine to make yellow light. At high noon the sun may also appear white, as the white light coming directly from the sun has the least distance to travel through the atmosphere and less chance to bounce of particles.
We explain why the sky is blue in detail in another video you can find in the description below and at the end of this video. (Why is the sky blue).
As the sun sets in our sky the light has a longer distance to travel through the atmosphere. The blue light starts scattering so much that the light does not end up reaching us. The light in the yellow, orange and red wavelengths have more chances to scatter on the slightly longer journey whilst still making it through to our eyes.
The lower the sunset the more dominant longer wavelengths will become. This is why the colours of sunsets get deeper as the sunsets more on the horizon, turning from yellow, into orange and finally, mainly just red hues.

My fifth hour class says that the cat's name should be Shadow.

[@BeautifulScience]

Great name, funnily enough I have a family cat called Shadow.

[@BeautifulScience]

Glad you agree!

[@Slate56]

Aaah, you can't beat a nice sunset. Cat............Sir Sooty.

[@BeautifulScience]

Sir sooty is well suited.

This channel is insanely underated. Keep doing what you're doing, I hope your big break comes soon! :)

[@BeautifulScience]

Thanks Wyatt!

Nature is so beautiful

[@2h_2n]

Just a slight correction at 1:18. The light is not really white light. It’s more accurate to say .... Earth's atmosphere acts as a light filter by scattering lights of certain wavelengths more and scattering some less. This phenomenon is due to refraction. In the afternoon, the Sun would appear white since there isn't much scattering. Thank you

[@katerineolmazabal5715]

Your channel is so cool! I find a bit irritating the commentary about the video of the color of the sky (which is pretty cool too,) I may have preferred a small link somewhere. I hope your channel keeps growing!!! Reminds me of Kurzgesagt. I think we need a lot more quality content like this in our lives

[@BeautifulScience]

Hey Katerine, thank you and appreciate the feedback! I will keep that in mind. But yes good quality science is my favourite part of KZbin :).

Interesting video sir.....!! ✌✌

Great video! Name the cat "Shadow"

0:52 the moment when I realized that the cat was Kiki's (Studio Ghibli's Kiki's delivery service) 😂👌

[@BeautifulScience]

Great spot my friend! Great film right?

[@GeniusEngineering]

I did not expect this video so soon. I like how this video tackled a similar topic than the previous and visually it was presented quite different.

[@BeautifulScience]

Thanks again! Yes I had in mind to have the two topics to compliment each other so thought it would be good to get them up at the same time!

[@rubyisanunknownauthor]

I think Oma might be a good name for the cat!

[@yokai3k]

hello may I have permission to get a short clip of the video for personal use only for school project Thanks a lot ❤❤🎉

[@Earlysgamer]

The name should be daisy

[@Renegen1]

this is the best explanation I got.

[@lilly07190]

The sunset tonight was so pretty, it was pink, yellow, blue and purple

[@daisiesonthelawn]

The cat should be called Midnight Star.

[@stefan_spataru]

Kiki is a perfect name for a cat.

That would be amazing, what sort of videos are you interested in?

I feel bad for the cat lol He said "Dreamy... now someone feed me already"

[@harrisonbanon9552]

This is beautiful

[@BeautifulScience]

Thanks Blue Sparrow!

[@jdini_]

Nice Explanation Nice Animation Incredible Video Though the comments the cat makes are a little bit too much, and don't add to the topic. But that's ok if most people like it right?

[@BeautifulScience]

Thanks for the feedback and compliments! I am working on the brand still and maybe I will tone the cats down a little going forwardm all fun and trial and error 😊😊

[@chrisjames4670]

Got any videos on chemtrails?

[@alakazamela]

The cat's name should be Vanta (as in Vanta black)

[@fabianaparedes124]

awesome

[@missiliacon5215]

I like the way u explain it , it was good !

[@BeautifulScience]

Hey Nor, Thanks for the nice words! Do you think the cats add to the video?

[@12342account]

a studio ghibli fan!

[@BeautifulScience]

Yes indeed! Great notice!

[@nastinkkafernandes1502]

This is so helpful

[@Hecatonicosachoron]

You should complete this series by explaining the green ray 💚

[@BeautifulScience]

Very interesting! I have another video lined up on the effects of blue light but you are right, will have to have a look at this as well :).

[@Hecatonicosachoron]

It's a fun phenomenon! It's also a novel by Verne which was made into a very nice and very loose and improvisatory adaptation by Eric Rohmer. But you might want to look into diffraction gratings and also colours on bubbles and oil spills after that, while you are doing an optics series.

[@BeautifulScience]

I actually have a list of video ideas and the oil spill one is actually one I already had down as an idea, (great minds ay). I have a few more optic and space related ones written up but might give this a whirl. Or even better, if you have script writing skills then get involved and drop me an email!

[@enzoehrhart5563]

Minks?

[@bananaforscale1283]

But why sky isn't purple then?

Thanks Jack.

right now the sky is orange yellow and white

[@crackingpirates4733]

now it will be hard to get more subscribers in youtube because youtube is overpopulated. but you must work hard until you reach high.

Thanks for the compliment and motivational comment. I will be working hard to grow the channel and appreciate your support :).

Name the cat Mr pexi

[@thirsty1629]

You remind me of Kurzgesagt. Are you two related by any chance?

[@BeautifulScience]

We were separated at birth! Ha, but thanks since I am one and they are 40+ that is very nice of you to say.

Do u even realize what u are saying..... the sun doesn't SET or RISE in our sky. i mean its 9 million miles away..... right?

[@BeautifulScience]

I think it is even more than that like 95million I think right? Obviously it does not set in reality but to us and our perspective it looks like it does of course, hope that makes sense? 😊

[@victorgiordano7581]

The name of the cat should be Matter, the dark Matter

[@BeautifulScience]

Haha nice! Think this is my winner anyway!

[@Pwnerest]

Question... How is "sun setting" even possible if you dont even take Flat Earth theory. Technically from a grand scale the sun never sets if the Earth is truly flat? and hence would leave the lingo of "some light" in the sky... not reffering to stars or the moon, im talking about some VISIBLE light that would brighten black.. you know... the negative spectrum? The fact also points that when you referring to "shorter" and "longer" light spectrum... it has NOTHING to do with the colors (which Is why I came on this pathetic 5th grader lecture). How does your position truly affect how you see light? If the colors from behind to front (N-S) and side to side (E-W) all have a different visible color that could range.. I again couldnt possible see the structure in how light ACTUALLY is "bending" unless there is a glass or some artificial doom (COUGH OPERATION FISH EYE'S) which still wouldnt be plausible knowing that AGAIN... THE EARTH CURVATURE ISNT REAL WHEN U GET MORE ADVANCE TECHNOLOGY TO "SCOPE" THE VIEW. ERGO.... HOW LIGHT "BEND" IF ITS CONSTANTLY AROUND US 24/7? Elon Musk or Clinton Snuff raffle. What ever you wanna call me just give me your god dam money or kill me.
