Before I get pounced on by academics from near and far, I just want to mention that I'm no longer a college student and never took a course in physics. All of my knowledge on the subject is practical and thus the answer to this eludes me. So in advance please forgive me if the answer to this seems elementary and/or a waste of time.
Hypothetical situation:
One day, an gigantic opaque barrier of some kind is placed between the Earth and the sun, completely blocking the view and the light of the sun visible from Earth for an entire hour.
In a period of a few seconds, that barrier is removed.
What would this situation look like from the perspective of an observer on earth? What does the sun look like before it's light has arrived on earth, can it be seen at all?
Would the observer still see the sun's light for minutes after the barrier had been put in place, as the remaining light particles finished their journey to the eye of the observer on earth?
