Question

Quizplus · Accepted Answer

Refraction of light as it passes from water to air causes objects under the water, like the bottom of a swimming pool, to appear closer to the surface than they actually are. This is due to the bending of light rays as they move from a denser medium (water) to a less dense medium (air), making the pool's bottom look shallower.
