when your child asks you something, you quickly need to refer to google dad to give you the answer
why does the sky blue dad?
Hang on a second, let me ask google dad,

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

uh, thanks dad,

is google dad my real dad?
let me check?
