Physics and life


What's the colour of nearby hills and faraway hills?
Why do they appear to have different colours even though they are all the same hills and viewed by the same observer?
Well, the red component of white light is more esaily absorbed when it travels through long distances and so farawary hills appear less red ( also less orange, yellow, green) and more blue.
