Rainbow is due to
absorption of sunlight in minute water droplets
diffusion of sunlight through water droplets
ionisation of water deposits
refraction and reflection of sunlight by water droplets
refraction and reflection of sunlight by water droplets
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. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
