i am having problem with the nature of light. The sun is lighting the earth. Suppose there solar system was emplty. Let's say we put the sun and Earth in their respective places in a experiment. So initially it will take 8.3 minutes to illuminate the part of Earth facing the sun. The Earth rotates and the dark part will slowly face the sun. My question is does it take again 8.3 minutes to light the first fraction of the initially dark part.
Suppose we have a continuous source of water like a pipe and let's say its hitting a sphere ball. Initially it will take some time to reach the ball. And as the ball rotates the water won't take time to hit it (the back part).
So is the light we receive during sunrise was given 8.3 minutes ago or is it otherwise, that as soon as we face the sun, we receive the light?
