RAINBOW
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.
. Light is refracted like light passing through a glass prism.
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
• 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.
•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.
• That’s the definition of rainbow, how does it happen, and how we can make it true.
