A rainbow is a natural wonder that takes place from certain features occurring. In order to have a rainbow occur, there must be a spectrum of light in the sky. This comes from a reflection taking place. A reflection is when the waves of light are mirrored. Refraction must also occur and it the light waves must turn to a different direction. This may take place with the reflection.

The last thing that must occur is dispersion which is the light creates a spectrum of different colors. However, a rainbow can be seen at night due to the moon. The light from the moon can cause the reflection, refraction and dispersion, but a rainbow caused by the moon’s light may not be colorful.

In different parts of the world, the seasons are different. People all over the world experience different types of weather even though they may be in the same season. For instance, people in China may be having different types of weather like cool weather, but during spring in the United States it may be warmer.

There also may be rain in the United Sates during spring, but tornadoes and heavy wind in another part of the world during spring. Often times, a rainbow is produced in the sky after a rainstorm.

The sun must be shining which doesn’t happen often after a rainstorm, but sometimes it does. During the monsoon season, there is a lot of rain and unusual weather. Therefore, a rainbow would most often be seen during this season.
