Why is the sky blue?
Blue light is scattered in all directions by the tiny molecules of air
in Earth's atmosphere
Blue is scattered more than other colors
because it travels as shorter, smaller waves
This is why we see a blue sky most of the time
The next one is
How do rainbows form?
A rainbow is a phenomenon
that is caused by reflection, refraction and dispersion of light
in water droplets resulting in a spectrum of light
appearing in the sky
It takes the form of multi-colored circular arc
Rainbows caused by sunlight always appear
in the section of light of sky directly
opposite the sun
and lastly,
Why is the sky red when it's sunset?
As the sun gets lower in the sky,
its light is passing through more of
the atmosphere to reach you
Even more of the blue light is scattered,
allowing the reds and yellows
to pass straight through your eyes
The next clip I'm gonna show is
the video of how this happens
