FORMATION OF RAINBOW:
The incident sunlight is refracted and dispersed as light rays from the sun enter water droplets that act like miniature prisms.
This light is then internally reflected within the droplet before being refracted again.
The seven-colored rainbow ‘VIBGYOR’ – violet, indigo, blue, green, yellow, orange, and red – can be seen as a result of the combined influence of all of these events.
Final Answer:
Hence, The Rainbow occurs when the incident sunlight is refracted and dispersed as light rays from the sun enter water droplets that act like miniature prisms and then the light is internally reflected within the droplet before being refracted again.
