»» THE FORMATION OF RAINBOW IS COMPLEX. ACTUALLY RAINBOW IS FORMED BY REFRACTION, TOTAL INTERNAL REFLECTION AND DISPERSION. WHEN SUNLIGHT FALLS ON THE RAIN DROPS THEN IT UNDERGOES REFRACTION, TOTAL INTERNAL REFLECTION AND DISPERSION.
RAINBOW CAN BE SEEN IF THE RAINING IS IN FRONT OF YOU AND THE SUNLIGHT IS IN THE OPPOSITE SIDE.

Answer:
A rainbow is formed when light (generally sunlight) passes through water droplets hanging in the atmosphere. The light waves change direction as they pass through the water droplets, resulting in two processes: reflection and refraction. When light reflects off a water droplet, it simply bounces back in the opposite direction from where it originated. When light refracts, it takes a different direction. Some individuals refer to refracted light as “bent light waves.” A rainbow is formed because white light enters the water droplet, where it bends in several different directions. When these bent light waves reach the other side of the water droplet, they reflect back out of the droplet instead of completely traversing the water. Since the white light is separated inside of the water, the refracted light appears as separate colors to the human eye.
