because molecules in the air scatter blue light from the sun more than they scatter red light.

Sky has no colour but it seems to blue from earth because when sun light enters in our environment the refraction is done and most of blue light ray reflected so it seems to blue
Kyun ki agar red ya green hota to accha nhi lgta
thats why sky is blue. if u look any natural ponds you will find sky black with star during day time.
blue colour is very refractive than other colours when it fall on atmosp. small subtance it spealt.
Due to atmospheric refraction yrr

Sky is white
Because of dirt

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 sky is blue.

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

I think this is write
When the sun high in the sky, this is why sky is blue. It appears a brighter blue that the farther away from the sun you look , because there is more atmosphere ( there fore more blue light) to see in those direction.
why is the sky blue. — because it reflects the ocean; because oxygen is a blue-colored gas; because sunlight has a blue tint — while the right answer is often thoroughly overlooked. In truth, the reason the sky is blue is because of three simple factors put together: that sunlight is made out of light of many different wavelengths, that Earth\’s atmosphere is made out of molecules that scatter different-wavelength light by different amounts, and the sensitivity of our eyes. Put these three things together, and a blue sky is inevitable. Here\’s how it all comes together.
