answered-by-expert Expert Answer

Rainbow is formed due to the dispersion of sun rays , when they fall on the suspended tiny droplets of water ( which act as prisms of small angles )  and it is visible to an observer having Sun at its back.

Hence the necessary condition for rainbow formation is presence of suspended droplets of water in atmosphere and sunrays ;  that is why , generally during a light drizzle we observe rainbow.
