Why is the sky blue? Thoroughly Explained Here!
This video describes the science of how Rayleigh scattering leads to blues and reds visible in the sky. It will incorporate ideas about white light, additive color, sun-Earth geometry, and scattering. Why is the sky blue? Search no further. Visit sites.google.com/site/dcaulfs... for more!

wow. this vid should win an award. spot on explanation. complete and thorough, as advertised. thanks
2019 and I’m just watching this. Phenomenal breakdown for someone who has trouble understanding the slightest things. I fully understand.

This solves tons of problem I'm encountering, millions of thanks.
Great explanation, This was not understood until 1881, when Lord Rayleigh showed that particles scatter short wavelengths more than longer wavelengths.
the best video I have seen explaining this. Thank you and well done. Absolutely great
this is the best explanation I've found so far, and there are many many videos on KZread about this topic... nice demonstration and good pacing. Thanks so much!
this is the best explanation so far. thank you. I like the slowness.
complete explaination! unlike other videos that only explains part of the problem.
ur the best teacher ever!!! Im 11 and i understand fully everything you said thanx
Thank you for this explanation! But now it is just after sunset and the sky appears dark blue. Why is blue visible again?
That was really well explained !!! Roughly better than many of those other videos that are trying to “ explain “ it .. Thanks man for your efforts
pretty much the best explanation of this topic after watching +20 vids
Finally an answer worthy of the complexity of the question! Great job.
Excellent explanation! Thank you for helping me see the light. (and thank you to my dog for typing this for me).
thank you for the very thorough explanation. I was a big fan of how you incorporated all levels of analysis
This is really good! You explained everything is great detail. This video should have 1,000,000 views.
Great video! You did a great deal less hand waving than other explanations I've seen.
Absolutely perfect!! This video explains physically correct "Why is the sky blue?" Almost all the other hundreds of videos on KZread on this subject are just plain rubbish. Congratulations!
Thanks for your detailed explanation !!
Excellent video, thoroughly explained.
Well, not only you did answer, but you did it almost literally at the speed of light XD Thank you for the clear explanation, now i have a bunch of new words to look for. Keep up the good work Marco
Perfect! Simply perfect! Keep up the good work. Subscribed!
Best i've ever seen you cleared my doubts
My good man.. you are concise and you're easy to understand. Thank you!
nice way of explanation .....loved it ....
Thank you for the really nice explanation..
Oh my Darwin that was beautiful! Thank you so very much for your hard work in sharing your knowledge and doing such a wonderful job.
Great video and animations! Thank you!
Thanks :) very simple and informative....
this deserves more view ! great video thanks !
this was so good! thank you so much for doing this!!!!
I enjoyied very much your explanation, and i learned a lot ! thanks =) please keep making videos
Wow. Excellent explanation.
Excellent video! It's a huge help! Thanks!
Best explanation ever!! Thanks!
Thanks a lot. Very good explanation.
perfectly explained!
Really informative (and interactive). Thank You.
Excellent, the best explanation on this topic.
You are a great teacher.
awesome Explanation!!!
I'm not sure that I completely understand, but uhhh, thank you all the same.
Great explanation!!
Well explained! Ty!
great explanation, but I wish you talked more about sunrise and sunset. So do reds and oranges appear in the sky because the suns lower and light is being effected by more atmospheric scattering? i'm guessing the red light is able to evade all of the molecules in its path and reach our eyeball while the blue light hits every molecule and scatters out of our site?
THANK YOU SO MUCH THAT WAS SO CLEAR AND SMOOTH!! HAVE A GOOD LIFE SIR!!
Great explanation...
this was perfect. thanks a lot.
Very well done, thank you very much!
Amazingly explained
great....i loved it
thank you. it was really great
very educative thank you regards
awesome video!!
brilliant.. haven't ever even when I was studying had come across this kind of explanation to understand this concept.. beautifully explained. Cloud contains water molecules which are bigger in size than the wavelength of the light photons, hence no rayleigh effect is observed the clouds and all colour photons pass through it in a straight line and thus the clouds appears white.
2021 thank u for this information 💜
Perfect explanation
Awesome ! big thanks
wow, great, super, excellent, splendid, awesome tutorial............
Thank you!
best explained!
awesome sir
God bless you for uploading such a valuable video.
Amazing thank you! I really liked the animation with the photon canons :p
Thank you! :)
cool..thanks for the answer.i was thinking of interference, diffraction n qm effects.
Amazing!!
Thank you very very much. ..... Now i have a good concept about light and colour.....شکریہ
Nice vid n thanks
superb
great teacher
Excellent
thanksss!! very good explanation...i hope im better at physics
please do more videos about why is the sky blue so that i can get the main point in defending my case study.
very helpful
Very nice
thank you so much
awesome vid
u ar my hero man !!!! i am speechless
Great video!! Does Raman scattering also takes place in this phenomenon? When does Raman scattering occur? Could you do a smilar awesome video for the colour of oceans?
Great thanks
thanks!
lol we have to watch this for our science homework. Pretty good!
Thanks for the video. Are you approximating the relation (I ~ 1/(lambda)^4) for relatively large wavelengths like visible light? Cuz I'm getting confused over this and Planck's function for the thermal radiation which is the correct explanation in comparison to the former relation.
This is amazing. I think the only thing that has me confused is the two different uses of intensity? We have intensity as in the chances of a photon entering your eye (proportional to 1/λ^4) and then we also have the intensity that decreases as photons are scattered. With the first, red light has a low intensity (well really is proportional to a lower number than say blue light) and so scatters less With the second, red light scatters less and so the intensity is higher or remains higher. Can anyone help with this?
thank you very much
Great explanation - my 9yr old son gets this now :-)
Thanks man
Great video, thank you! Why is the sky much lighter near the horizon during the day? If you are looking at the horizon during the day then are you not looking through more of the atmosphere (like at sunset) so why is it pale blue/whitish?
viva well done
nice video. :D
great video.. but I had a doubt .. Is rayleigh scattering the same as tyndall effect?
I think the light is being "scattered" due to electromagnetic oscillation of a molecule -- a more energetic photon will cause more oscillation to molecules that it travels near and therefore more "scattering".
Thanks. :)
Wow this is so cool! So this is also why clouds look extremely pretty in highly polluted cities at night, yeah? All of the particles in the pollution will scatter basically every blue and green light ray (obviously not all of them, but you get the picture) and the clouds will appear almost pure red?
amazing video now i under stand
so it means that travelled distance has some important role in the equation....is there any equation taking distance into account?
when you said deflected or scattered you mean that the photon is absorbed by the molecule and remitted ? thanks in advance.
And how would everything be if the sky wasn't blue but transparent? Would we be living like in a dome, seeing blackness far away while looking above us? Would it get darker cause instead of blue sky we'd have black space?
