Document Summary
How much water vapor can in the atmosphere are control by the temperature of the atmosphere. But the water vapor in the atmosphere will increase more than 10 units. They come in the same door, but it goes out with the different door. The shortest wave length is gamma rays, then x-ra(cid:455), ultra(cid:448)iolet radio. We have different colors in the air depends which part of light will come into our eyes. We also emit radiation but they are non-visible. The solar and terrestrial radiations graph, the earth radiation cannot see at all because only 1/16000, but the sun has (20)4: the greenhouse gases selectively absorb certain frequencies of radiation.
