why sky appears blue

it is of 4 marks plz give more points

Answer 1

This is because the white light from the sun is a mixture of seven colours and during day the molecules of air scatter blue light from the sunlight.. so the sky looks blue.

Answer 2

Sun has white light it can split into seven colors as Violet, Indigo, Blue, Green, Yellow, Orange and Red. Violet has shorter wave length Indigo has more than Violet and increases. So Blue color can reach our Earth as white light and it is refracted by the Earth's atmosphere. So the sky appears blue in color.
