"Mummy, why is the sky blue?"
"Well dear......
The sky appears blue because of an effect called scattering.
In the atmosphere, the molecules absorb blues light better than the longer red wavelengths.
Then by sending the light in different directions, the blue light is scattered all around the sky, making it appear blue.
As the sun sets, the light has to get through more air to get to your eyes.
So more blue light is scattered which leaves more red light to reach your eyes.
That is why the Sun and the sky around it look red at sunset and sunrise."
"er, ok mummy.."
