To see the bottom of a well, light would need to be Blank from the water's surface and travel up the well to our eyes.target 1 of 4
If the well is much deeper than Blank, this is not likely to happen for two reasons.target 2 of 4
First, few rays of light from natural sources (Blank) are oriented correctly with respect to the well to travel to the bottom of the well.target 3 of 4
Second, those few rays that make it to the bottom are unlikely to be Blank in a direction that would allow them to escape the well. Thus, very little light from the bottom of the well arrives at our eyes, so the well appears black.
