The sky is not blue it's light blue: it is a combination of different scattered colours that are interpreted together by our imperfect vision as light blue. It's true, there is less violet in the light reaching Earth from the sun but violet is so much more scattered we would still see the sky as violet if we had cones in our eyes that were specific to that colour. Brian Cox's, Tyndall's and Rayleigh's explanation about dust bouncing blue light the most has nothing to do with it, they're wrong.
Sounds a very simple question - this is not meant to sound big--headed but we've only just covered it in the third year of a Physics degree so the answer is NOT simple!
pourquoi le jaune d'oeuf est jaune c'est exactement la meme question que pourquoi le ciel est bleu mais est-ce que nous avons la bonne visons du ciel car certain animaux voit le ciel d'une autre couleur.
Okay, forget about the accumulation-atal-anal-fantantical crap.... heres a SIMPLE way of saying why the sky is blue. The sun sets its rays on the ocean which was not said in the video. The suns rays refelct the blue color from the ocean into the stratosphere or higher. That is why we humans see blue in the sky . FROM THE OCEAN........ Then again.. why don't we see blue in the sky at night. Yet, the sun uses its rays at the moon, reflects the color on the ocean.. but its still black...
One month later he said. The spectrum is the 7 seperate colors that white light is composed of. Aim a glass prism at the sun.White light goes in and seven colors come out the other side. That is the spectrum of light. The sky is blue as a result of light rays reflecting the blue end of the spectrum back at us. I do believe that is the best answer ever given in the history of the world. Not bad huh!
There is no object up there. "The Sky" is an illusory surface. Illusory=nonexistant.
The only thing up there is air. Heh.
Why is aerogel blue? Why are bluejays blue? Why are certain opals blue? Because of freq-selective scattering.
So. Why is air colored blue?
That's when the screaming starts. "AIR ISN'T BLUE, IT'S INVISIBLE!!!" Nope, wrong. The only thing up there is air. "Sky" doesn't exist, there is no surface up there. The blue color you see? That's air.
Isn't his point that the sky is blue because short wavelength light is more likely to smack into the small gas molecules & get reflected, whereas red & green with their longer wavelength tend not to get so scattered?
If that's the case (its all down to the wavelength of the light) & the suns light is white (an equal-ish mix of all wavelengths) then WHY ISN'T THE SKY VIOLET???
Indigo & violet have shorter wavelengths than blue, but the sky is clearly BLUE, not VIOLET!

@ThePokermong Because the Sun actually does not contain equal parts of each gap of color. Instead, it is formed slightly more by blue-green light and less violet and red. Thus, even though violet light IS scattered and gets back to us, the amount of it is so little it barely affects the final resulting color. Furthermore, human eye is also much less sensitive to both violet and red frequency, so we see even less violet than what is reflected.
@galaxy91 Haha thank you G-91, But, if you were a real fan of the Wutang Clan you'd know what I meant. That is a lyric off the GZA's album "Liquid Swords"; Most definitely one of the best hip-hop albums ever. On the track '4th Chamber' Ghostface says: "Why is the sky blue? Why is water wet? Why did Judas rat the romans, while Jesus slept? Stand up, you're out of luck like two dogs stuck. Iron man, be sippin rum, out of Stanley Cups.." Thanx 4 the definition and not being a mindless hater tho
I think kids should look up information rather than using youtube conversations to learn about things, The google bar is like 8 inches away from you people.
@rebeliouslizard Water is clear dumbass. The ocean reflects the sky. like andrewmax123 said "
2 weeks ago 7 The more in depth reason for why the sky is blue is because the natural frequency of nitrogen which is the predominant gas in air is the same frequency as the color blue. So the nitrogen scatters red and green and reflects blue. "
What causes prisms in the sky I see them a lot!......On hot sunny days round shapes and other shapes and the clouds seem to copy the shape of the prisms over and over?
I learned during a science far that a colour absorbs that sam colour (red absorbs red) so does that mean grass is actually red but reflects green? Or was I mislead?
@BlackPuma51 The color we *see* of an object depends on what colors the object absorbs and what colors it reflects. So, an object you see as red reflects red light but absorbs all the other colors.
The color an object "really is" depends on your definition of "really is", but it only makes sense to say an object is the color we perceive it to be - so grass is green.
me was always told that the blue you see in the sky is actually the reflection of the oceans. And the red of the sunset is caused by all the pollution in the air. This as the sun is lighting much more of the earth's surface when it sets than when it is up in the sky at noon.
who chose this girl for this segment?? I'm pretty sure it's the same person who chose the person to answer the question. The girl and the science guy are not individually okey, and they showed them together within 3 minutes. wake up discoverynews!
After watching this, i'm going back to because-god-did-it-that-way explanation.
@CJAEY LAWL you're funny. Just cause you learned this :). I betcha everybody knows something noone else knows :D. Don't be mean and call people idiots.
@CJAEY i dont do grades.. we have like year 7 and year 8 not grades and i belive thats different.. im in yr 8 im 12 yrs old... am i in 9th grade? lol i dont know
Why tell me why did you have to find the answer from this guy??? It's more confusing now.. I understand that the different colors are a reflection of light, but his answer just leaves your jaw dropping saying WHAT????????
i think he messed up with his explanation i think that at 1:39 he meant to say red and green light is absorbed while blue light is transmitted from the sky
Dude this guy was horrible at explaining this shit.. haha! Speaking all stumbly and stutters.. its just painful to listen to. He cant even talk without pausing everywhere and "uh eh uhm".. they could do better.
The more in depth reason for why the sky is blue is because the natural frequency of nitrogen which is the predominant gas in air is the same frequency as the color blue. So the nitrogen scatters red and green and reflects blue.
black IS NOT A COLOR, its the absence of LIGHT you cant have color without light, why do you think when you put your hands over your eyes all you see is black because there is no light reflecting any color back for your eye to see. hell why is space black? why is a black hole black? because a black hole sucks all light in making no light at all, thus meaning without light no color.
@bozy99 there is green right when the sun goes away it is almost impossible to see it has a specific name effect, like in pirates of the Caribbean 3 but i doubt it would be that bright :)
@bozy99 well if you refer northern lights thats different, but different colors have different wave lengths like from strongest to weakest. for instance if you have a cd/dvd and you put light on it, it reflects as a rainbow on a wall and you can see blue is short and red is long :)
@lars0 Black is not a color, it is an absence of all light. What you are talking about is a color system used for printing where colors are combined and this show is about real light which doesent work that way.
@andymudnic black is not the absence of color at all, black is the result of an object absorbing the entire spectrum. White it the result of no color being absorbed.
in a way you are correct, but your wording is off
@deafomega Well there is really no point in debating because the anwser really depends on the way we define color. If we define color as a part of measurable visual spectrum then black is not a color since black is lack of any part of that spectrum that reflects back into our eyes making it visible. But if we define color as something non-physical, like the image or impression our brain creates, then we can say that black is a color. Blah,
@lars0 Are you thinking about light or paint? Green's green... it's only a mixture of two colours when it's blue+yellow in paint. In light, green's a primary colour, not a mixture
1) Look for a scientific answer but keep in mind that you will have to use your brain in order to understand the answer!
2) Rely on the christian answer SIMPLE ANSWER: The sky is blue because god made it blue! He made it a happy color so his children would be happy when they looked into the sky!
@99minerkc blue doesnt make everyone happy. some people hate the color blue. A better question is, why isn't the sky the color we would want it to be?
@yoops me black paint is not black lol); Black is simply defined as the absence of light in Physics (dont know when did i say something against it, I was talking about "color")
@yoops how did i define color? Can you quote my words? I said color is subjective which means its definition depends how you apply the word color. Your artificial balck is just an example of the color black. What i wanted to say is Black can be simply classified as a ""color"" and ""not a color"", which depends how this black is apllied as color is a subjective word (i repeated it twice). Black is a color in the Art World if your example is true(dont tell
This is the second video that I see from this channel... are all of their videos such huge fails? I would like to know, although sure as hell I am not going to try to find out.
@supervalfar true. but you aren't thinking it through a red-orange-yellow-green-blue-indigo-violet (the rainbow) perspective. The 3 main colours, considered by physics, are red green and blue (as opposed to artists who consider them red yellow blue). Therefor if you absorb red and blue, that only leaves green in the main spectrum.
he made a mistake. he said the green and red are unaffected by the passage through the sky...but they are...they're absorbed. he meant to say BLUE is unaffected.
BTW: he didn't explain anything...WHY are red and green absorbed by the atmosphere!
Does anyone know or can hazard a guess about how many %'s of the sky is illuminated by the sun at any 1 time ?

1) Look for a scientific answer but keep in mind that you will have to use your brain in order to understand the answer!
2) Rely on the christian answer SIMPLE ANSWER: The sky is blue because god made it blue! He made it a happy color so his children would be happy when they looked into the sky!
Which answer do you embrace?

@99minerkc blue doesnt make everyone happy. some people hate the color blue. A better question is, why isn't the sky the color we would want it to be?

@yoops me black paint is not black lol); Black is simply defined as the absence of light in Physics (dont know when did i say something against it, I was talking about "color")

@yoops how did i define color? Can you quote my words? I said color is subjective which means its definition depends how you apply the word color. Your artificial balck is just an example of the color black. What i wanted to say is Black can be simply classified as a ""color"" and ""not a color"", which depends how this black is apllied as color is a subjective word (i repeated it twice). Black is a color in the Art World if your example is true(dont tell

So, you guys are bored?
What the hell did you think was going to happen in the video? Rock concerts, circuses and flying llamas with androids?
No, its just a simple science lesson.

red and blue don't makes green ! ! ! yellow and blue makes green : )

@supervalfar true. but you aren't thinking it through a red-orange-yellow-green-blue-indigo-violet (the rainbow) perspective. The 3 main colours, considered by physics, are red green and blue (as opposed to artists who consider them red yellow blue). Therefor if you absorb red and blue, that only leaves green in the main spectrum.

The Sky could've once been orange during Earths first billion years due to the amount of methane in the atmosphere.

People hate HARD on youtube, the comments section has just provided a forum for tools to say silly ass things behind the protection of log in names.
And now even I'm doing it, stop the hate or post a better video.

he made a mistake. he said the green and red are unaffected by the passage through the sky...but they are...they're absorbed. he meant to say BLUE is unaffected.
BTW: he didn't explain anything...WHY are red and green absorbed by the atmosphere!
