3. Rainbow is a natural phenomenon that
is so impressive. This phenomenon
often appears after rain. Rainbow is
an arc spectrum which is so large and
occurs because the drops are
refracted by sunlight.
When the sun is shining and the light
passing through water droplets, then you
will see a refraction that causes a wide
variety of colors
. Light is refracted like light
passing through a glass prism.
4. • Other names of the
rainbow is a rainbow
which is a symptom of
optical and
meteorological
phenomenon in which
light with different
colors refracted
parallel to each other
into water droplets.
You can also see this
phenomenon under
the very high and
heavy waterfall.
6. • All the happenings begin when the
sunlight passing through the
raindrops. Then the light is deflected
to the center of the droplet. The
white light, now separated from each
other into a spectrum of colors.
7. • The process does not
stop there. The colors
that have been
separated, then separate
again into the very small
portions. There is more
light separated from
each other in the
droplets. Then there are
more curved and finally
those color form a light
curve called a rainbow.
9. • Of course. There are at
least two ways that you can
do to make a rainbow. First,
you can use a spray
containing water. We know
that rainbows occur when
sunlight passing through
the raindrops.
10. • So, we make our own rain
droplets from the water spray.
In the morning or afternoon,
spray water under the sun,
then see the water droplets
flying. Spray lots of water and
you will see a small rainbow
that you can touch easily.
11. • Second, use pieces of video discs
then reflected to the light of the
sun, and navigate to the wall or
ceiling of your house. On the
ceiling or the wall, you will see a
colorful light that have the same
color with the rainbow.
12. • That’s the definition of
rainbow, how does it happen,
and how we can make it true.
