Question
If you could look only at the light after it had beenreflected, say by the sea ( and NOT AT ALL at the directradiation). what would you see? II know that the sky is blue because the sunlight isreflecting off the water, but I don't know if that is what theproblem is getting at.

The sky is not blue because of sunlight reflecting off water. The sky is blue because the sun scatters blue light more than it scatters the other colors. You can view direct radiation by looking at the sun (not safe to do), or by looking at a lightbulb. You can not see the direct radiation otherwise. Consider looking at the moon in the night sky. The sky next to it is black. It's not because light doesn't go there. It's just that none of this light gets reflected back at you, so you see nothing. So if you couldn't see direct radiation at all, everything would look normal, except you couldn't directly view the Sun or light bulbs.
