Rainbows are one of the most interesting natural phenomena. Apart from its beautiful color, it is also because of its appearance which usually cannot be predicted directly by humans.
All we can predict is that the rainbow will appear especially when the sun shines again right after the rain, usually at times like this the rainbow will appear when viewed from a certain angle.
What is a rainbow?
For more details regarding the explanation of what a rainbow is, Mother can explain the following to the Little One. Quoted from the website Ministry of Education and Culture Learning ResourcesA rainbow is an optical and meteorological phenomenon that causes a (almost) continuous spectrum of light to appear in the sky when the sun shines on a falling raindrop.
The order of the colors of the rainbow was first discovered by Isaac Newton after experimenting with describing sunlight using a prism. This experiment was carried out by refracting white light on a glass prism, which resulted in the decomposition of white light into seven color components, namely red, orange, yellow, green, blue, indigo, and purple.
According to Newton, indigo is a color between blue and purple, the rainbow consists of all sorts of colors that can be seen by the human eye. Until now, it is not known exactly how many colors there are in the rainbow.
It is said that the human eye can distinguish up to 350,000 different colors. The number of colors in the rainbow can be summed up into seven colors, namely red, yellow, green, blue, indigo and purple, or commonly abbreviated as Mejikuhibiniu.

The order of the colors of the rainbow and their meaning
Actually, the colors in the rainbow consist of various colors that cannot be explained scientifically. Basically the order of the colors of the rainbow has seven colors, namely red, orange, yellow, green, blue, indigo, and purple.
In the human body, color acts as a cell balancer for healing. That is, we need certain colors to live in harmony. Each color in the rainbow has a role in the body.
Light and color are part of the electromagnetic spectrum that is sensitive to the human eye and are also part of the energy spectrum that facilitates the survival of every creature on this planet.
Why does this sequence of colors appear on the rainbow?
Here’s the explanation as quoted from the website: USGS. Do you remember the experiment you did when you were in school? Maybe at school you did an experiment where the teacher shined white light through a triangular glass, or a prism. When white light penetrates the prism, the white light that emerges from the prism will be divided into several individual colors with different colors.
The colors that come out of the prism, and also like what happens in a rainbow are from light, which means that in a rainbow it is sunlight that will produce the colors of the rainbow. Sunlight is white light, but white light actually contains all the colors of the rainbow that you are ready to see, but mixed into one. Light has a wavelength and each color of light has a different wavelength.
When light enters the glass, which is denser than air, it slows down and is bent, with different wavelengths that make up white light that is bent at different angles and will produce different colors, as is the result of the rainbow color, which is red in the sky. one side and turn purple on the other.
Why do rainbows have colors?
This happens because rainwater refracts light from the sun into a spectrum of colors. A prism does the same thing.
A similar situation occurs in raindrops. Water droplets act like prisms, except that light is refracted at three different points (some light bounces off the back of the raindrop and returns to your eyes as you watch the rainbow).
Each time a light beam bounces off, it becomes wider, and the rainbow you will see is a combination of millions of light rays that are captured by your eyes again.
That’s an explanation of the rainbow and the order of the colors of the rainbow that you can use as a material for discussion or experimentation with your little one at home. I hope it’s useful, Mom.
