Answer 1

Answer:

Explanation: When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow.
