A rainbow is always formed in a direction opp to sun . The water droplets act like small prisms . They refract and disperse the incident sunlight ,then refract it internally and finally refract it against when it comes out of rainbow .Due to the dispersion af light and internal refraction ,different colours reach the observer`s eye

A rainbow is formed, because water droplets in the atmosphere breaks sunlight into several colours (i.e) the water droplets acts as a prism.
When light meets a water droplet, it is refracted at the boundary of air and water enters the droplet,where the light dispersed into seven colours.
