The observed position of a fish in a lake differs from its actual position because:
light bends as it passes from water to air, causing refraction
the fish moves too quickly to be seen accurately
the water distorts the image due to waves

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