Rainbow is a combination of refraction, dispersion and total internal reflection of sunlight. In sky, prism like objects are needed for the dispersion of light. After rainfall, tiny water drops suspended in air act as prisms. The rainbow's appearance is caused by dispersion of sunlight as it is refracted by (approximately spherical) raindrops.
The light is first refracted as it enters the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop.Their colors come from raindrops that reflect sunlight, breaking white sunlight into colors .
Sunlight is made up of many wavelengths so that makes us see the colors of the rainbow.When the light enters the water, it bends causing its shape.
