Question

how is rainbow formed

Answer 1

Hey mate!

here's your answer:

Actually, 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.

Answer 2

a rainbow is a meteorological phenomenon that is caused by reflection,refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky
