Define rainbow.How is it formed?
Doraemon12:
it is a combination of different phenomena dispersion , refraction,and reflection of light .The rainbow appears in the sky after a rain shower .The water droplets act as a small prisms . When sunlight enters the water droplets present in the atmosphere ,they refract and disperse the incident sunlight. Then they reflect it internally inside the droplet and finally again refract it.As a collective effect of all these phenomena,the seven coloured rainbow is formed.

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. It occurs when the droplets of water act as a prism opposite to the direction of the sun.
