Rainbow is a natural phenomenon that appears as an arc of colors in the sky after rain. It occurs when sunlight passes through water droplets, refracting and separating white light into different colors. The light is refracted when it enters the water droplet, reflects off the inside surface, and refracts again when exiting. This causes the different wavelengths of light to separate into distinct bands of color forming an arc. Rainbows can also form under heavy waterfalls due to the same optical phenomenon of light refraction and dispersion through water droplets.

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.
How rainbow formed?

explanation
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.
How does rainbow happen in detail? 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. 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.

5. Squenced of
explanation
Can we make a rainbow? 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. 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
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.
Closing
That’s the definition of rainbow, how
does it happen, and how we can
make it true.
