any other electromagnetic reason for their differences in color?
*A: None of the planets radiates in the visible part of the electromagnetic spectrum, although Jupiter radiates quite a bit in the infrared. The reason that different planets are different colors is that different chemicals reflect different colors differently. For example, ferrous oxide (rust) reflects redish light better than any other color. Thus Mars, which is covered with the stuff, appears red when sunlight is reflecting off of it. Methane and ammonia reflect the color blue best, hence the color of Neptune. Q: One aspect of chapter three that confused me is why we can only see a small portion of the light scale. *A: While we only see a small portion of the light scale, it is the portion that the sun emits the most. Evolution and natural selection have favored lifeforms which can see the best in the type of light which is the brightest. Lifeforms which could see, say, in the infrared but not the visual range couldn’t see as well because the sun isn’t as bright in the infrared as i
