Question

What is the colour of the clear sky during day time? Give reason for it.

Answer 1

Colour of the clear sky is blue, because molecules of air scatter blue light from the sun more than the scattered red light.

Answer 2

The colour of the sky is always changing according to the season, current weather and time period of a day.

In the clear and normal weather condition the colour of the sky in the daytime is mostly sky-blue.

Because the air molecules of our atmosphere reflects the blue light of the solar spectrums more than any other colour.

That's why it appears blue.
