A person observes a fish in a lake. The position of the fish is shown.

Which statement best explains why the observed fish appears to be closer to the surface than the actual fish?

• When light travels from water into air, the changes direction.

• The light bounces off of the water and creates a reflected image of the fish.

• When white light passes through the surface of the water, the light separates into colors.

• The light enters the water and exits the water at the same angle.
