why is the sky blue

Report as

Sunlight is a mix of all the colours of the rainbow. Light is a spectrum of light of different wavelengths, from the shorter "blue" to the longer "red" wavelengths.

When sunlight enters the atmosphere, the molecules in the air are the right size to "scatter" the blue wavelengths of the sunlight, which sort of "paints" the sky blue.

The reason the sun appears yellow to us is because some of the blue light has been removed by the atmosphere so there is less blue in the sunlight that reaches the surface (white sunlight minus some blue makes yellow sunlight).

Because when the sun's rays hit the particles in Earth's atmosphere, (light is a rainbow blended together to look white) and only blue shines through, and therefore the sky is blue. Understand?
