Solution
A rainbow is often acknowledged as one of the most beautiful light displays ever seen on Earth. Rainbows have been formed by the reflection, refraction, and dispersion of light among water drops after rainfall. All of these events combine to form a light spectrum throughout the sky recognized as a rainbow.
There are two types of rainbows:
Primary rainbow
Secondary rainbow
Primary rainbow:
The main rainbow is created by one entire internal reflection as well as two refractions of white light involving water droplets.
Secondary rainbow:
A secondary rainbow is formed by two entire internal reflections as well as two refractions of white light by water droplets, it has a brighter color than a primary rainbow.
Therefore, the rainbow is a multi-colored arc generated by the collision of light with water droplets.
