What do you know about rainbow?
We can see it in many colors combination such as red, orange, yellow, green, blue, indigo, and violet.
If you read about the title, you might be wondering this several questions :
1. What is Monochrome Rainbow?
2. It is black-white rainbow?
3. Or is it just one colored rainbow?
So I will tell you about monochrome rainbow.
- Monochrome or red rainbow is an optical and meteorological phenomenon and a rare variation of the more commonly multicolored rainbow.
Its formation process is identical to that of a normal rainbow (namely the reflection/refraction of light in water droplets), the difference being that a monochrome rainbow requires the sun to be close to the horizon; i.e., near sunrise or sunset.
- Then why the color is red?
Red Rainbow happen when the sun is on the horizon. They're created for much the same reason that a sunset or sunrise looks red. Because, when the sun is low, the blue and green of its rays are weakened by scattering during the long journey to your eyes through Earth's atmosphere. The red light travels through more directly. And that's it you see a red rainbow.
It happens when you're watching a sunset, and there's rain in the air, turn in the direction opposite the sun and watch for the elusive red rainbow. But it is not certain because red rainbow is a rare.
