Question

why the sky is in blue colour​

Answer 1

Answer:

Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Also, the surface of Earth has reflected and scattered the light.
