Hi, Norhan. I like your picture of the two skies.
Norhan: Thank you, honey, I tried.
Dhoha: But I noticed something in your picture and in our real sky.
Norhan: Really? What is it that you have noticed with your keen eye?
Dhoha: I've noticed that our sky is blue and our sunsets are red. Do you know why?
Norhan: Why, yes, I do know why. I will tell you a story explaining the physics behind the sky.
Once upon a daylight's view,
Scientists questioned everything they knew.
but they didn't have a single clue,
of how or why the sky was blue.
Scientists noted everything they found,
when they were asked this question, no one made a sound.
it wasn't until the year of 1871 when lord Raleigh came around,
and answered the question reading from his paper mound.
To answer this, we gotta' understand what is light,
and that because of light, we have sight.
Being able to see things that are dim or bright,
is all because our eyes reflect off of light.
The sun's light is white, but is not what it may seem
it is actually the colors of the rainbow united in a single beam.
Red, orange, yellow, and green have longer wavelengths than the rest of the team.
Where as blue, indigo, and violet have a shorter wavelength theme.
when this beam of light is in our atmosphere,
it encounters all kinds of particles in the air far and near.
The colors are then divided up, and blue is the one to cheer,
because it is the one that is scattered in the atmosphere,
giving our sky the beautiful blue that is so clear.
The Rayleigh Scattering was the title of this new finding, a scientist read,
Quickly, the explanation of why the sky was blue began to spread,
Until one day someone asked a question and said:
"Does anyone know why sunsets are red??"
Everyone went silent, until one rose to answer,
He began to speak: "Let's analyze this chapter."
His hand got a marker, and began drawing on the board, moving like a dancer.
In a matter of minutes, he explained it like a master.
"As the sun moves along our atmosphere," he said,
"blue light is mostly scattered, and colors with longer wavelengths are absorbed and left instead.
So yellow, orange, and red are the ones that spread.
Making our eyes see a magnificent red."
Thanks to lord Rayleigh,
In a matter of minutes, we figured out the mystery of the sky.
And how the sunlight reflects off of the eye,
this is just conceptual physics that we apply.
Norhan:Now you should be proud because you learned something new,
about how or why the sky is blue.
and if somebody asks you why are sunsets red,
hopefully, you remember my explanation and what I said:)
