Why do objects viewed underwater with a mask appear closer and larger than they really are?
◦ Light traveling through the water scatters more than it does when moving through the air.
◦ The mask provides additional refraction of light before it reaches the retina.
◦ Light moves more slowly through the water.
◦ The cornea does not function in water, and the light is not refracted as much.
◦ Water is denser than the lens of the eye.
