Rainbow is a natural phenomenon caused by the refraction and reflection of light in water points to the appearance of a spectrum of light in the sky. Rainbows appear in the shape of colorful arcs. If it is caused by water and sun, a rainbow appears on the side of the sky directly opposite the sun. where they can sometimes be full circle, but for them the average observer, only an arc will be visible.

The colors in the rainbow are found in the spectrum of white light colors when splitting. There are seven main colors in the rainbow including red, yellow, green, orange, blue, indigo and purple. The moment the sunlight touched the water droplets, seven colors appeared. As sunlight moves from air to water, the color of the light slows down to varying speeds depending on the frequency. Then when the purple light entered the raindrops, it turned at an acute angle. On the right side of the water droplets, part of the light is passed back into the air, while the rest is reflected back. The raindrops higher in the sky disperse the light so that only the red light is visible to the observer's eye. Droplets between red and purple reflect different colors so that the observer sees the full spectrum of colors.

The sunlight that hits the raindrops in the atmosphere is refracted on the surface of the raindrops until they enter the droplets. After refraction, the light breaks into seven colors in the raindrops, then reflected to the other side of the raindrops after traveling in them. When the light in the raindrops is refracted, a spectrum is formed to make the seven colors of the rainbow appear. During reflection, the angle (reflection) is equal to the angle of incidence which means that the reflected light travels along the specified path and maintains the difference in angle bias. So in conclusion a rainbow is a group of raindrops hanging in the atmosphere that divide sunlight into seven colors, like a prism.

The process of natural flooding is preceded by rain which falls to the surface of the earth. Then the rain water is absorbed by the ground surface and flows to the lower place. Once that condition happens, evaporation and the water appear to the surface of the land.

Flooding can be disastrous for humans when floods happen in an area that people live because the water carries along objects like houses, bridges, cars, furniture and even people.

On the other hand, the process of non natural flooding is usually caused by bad habits of humans who do not care about the environment, such as littering that can make water flow clogged.
