Why is the sky blue ?
actually, the sky isn't blue, it is purple
to make sure of these colors, let's go out to observe its color
as we're seeing now, the sky is blue, not purple as anyone has said before..
but actually, we are not seeing the sky with its true color,
and we'll know all of that, when we go to the studio,
the color you're seeing now is blue, i wanted to make sure of that ..
To the studio.
Why is the sky blue, is a question we all did ask, as we lived on planet Earth, which is 4.5 billion years old..
to know the answer of this Question, we must know that...
Earth's atmosphere is 21%Oxygen, and 78% Nitrogen, in total they represent 99% of the atmosphere ..
the light coming from the Sun is a white light, contains the 7 colors of the rainbow,
as we can see when a white light goes through a prism, we can see red, orange, yellow, green, blue, indigo and violet
the longest wave-length is Red, and the shortest wave-length is the violet
the violet is shorter than blue in wave-length..
that's why we should see purple skies.
as we began to study the wave-lengths of the different colors..
we discovered that the most colored that scatter through Earth's atmosphere is blue and violet..
as they collide with the molecules of oxygen and nitrogen spreading around Earth's atmosphere..
That follows the concept of, Rayleigh scattering effect,
which says, the blue wave-length scatters 16 times more than Red wave-length
So, the sky must be purple, as the violet is the shortest in wave-length..
WHY THE SKY ISN'T PURPLE ?
That's a result of the human eye design..
the human eye can see in the middle of a light spectrum best, and blue is near the middle area more than..
the violet color.
That is why you see blue skies :)
