Why does sky look blue on a clear day​

Answer 1

Answer:

becoz the light rays coming from the sun having seven different colours..the red travels fastest in fog and will be visible to us on the day as the sky is red and in the mid day the blue light travels directly into the earth making it a clear blue sky at mid day

Answer 2

Answer:

Blue light waves are shorter than red light waves. Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. ... 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.
