____ 12. In the picture below, the person sees the image of the fish in a different location than the
actual fish. This happens because:
the fish moves very fast from one place to another.
the water absorbs some of the light rays reflected from the fish.
the light rays reflected from the fish bend at the surface of the water.
the water acts like a mirror and bounces the light rays back down to the fish.

b.
c.
d.
Ray a
Ray b
Ray c
