Question

why the sky appear blue or the sun appears raddish at sunrise???​

Answer 1

Answer:

the shorter wavelength scatters more and our eye is more sensitive to blue colour. So the sky appears blue. We observe the sun red at the time of sunrise and sunset because the Red colour is least scattered. So by the time light reaches the surface of the earth all the colours except red get scattered away.
