Why is the sky blue?
The shades of the sky
Looking at the Eath's surface, the sky
 on different colors depending on the
 time. If day, displays a blue; if at the
 end of the afternoon, reds win; if
 night, turns black.
We see the sky
Astronauts always see the dark sky. So
 why do we get to see blues, reds and
 oranges? Have you ever stopped to
 think about it?
History
Because all this happens because of the
 way the light scatters through the
 atmosphere! It may seem strange, but
 the light is a form of energy that
 travels through space like a wave. This
 same: a wave! That only a very small
 wave: to find the length of a wave of
 sunlight, for example one millimeter
 would need to divide into a thousand
 equal parts.
A popular saying curious
The proverb says: that size does not
 matter does not apply to light. You know
 why? For the size of the wave
 described by this form of energy
 determines exactly the color she has.
 The smaller waves are blue; the longest
 waves are red.
Experience
Have done an experiment with a prism?
 The prism is na object made of glass or
 crystal used to decompose sunlight. I've
 Certainly heard of that white light is
 the union of all colors, is not it? For
 white sunlight just being formed by
 waves of different sizes. With the help
 of a prism, we can see the colored
 beams that form.
The sunlight
When sunlight reaches Earth, it
 encounters na obstacle: the
 atmosphere, ie, the large mass of air
 that envelops the planet. By bumping
 into air molecules, waves of different
 sizes begin to spread each one way.
 Waves of short length spread. And what
 color the smallest light wave? Exactly:
 blue!
The waves
This mechanism also explains the color
 variations in the sky. In addition to the
 air molecules are suspended in the
 atmosphere, dust particles. When these
 particles are smaller than the
 waves, causing an even greater spread
 of light. The blue waves spread far, you
 end up diluting, allowing us to see the
 longest waves as red and yellow.
We hope you enjoyed!
