Question

Why is the sky blue?

Answer 1

Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors I. e:-VIBGYOR 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.

Sky is blue because molecules in the air scatter blue light from the sun more then they scatter red light.When we look at the sky at during sun set ,we see red and orange colour because the blue light has been scattering out away from the line of sight.Thats why we see the colour in red and orange during sun set.

I hope it will help for u ☺.

Answer 2

hi friend ..........its just easy one 
the first reason
               is reflection of light
the second reason is 
               "The ocean looks blue because red, orange and yellow  are absorbed more strongly by water than is blue . So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue."
 hope the answer is helpful
