Question

why the sky looks blue?

Answer 1

A clear cloudless day-time sky is bluebecause molecules in the air scatterblue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
