When I look at things underwater, they often seem _____ than they look on the surface.

When viewing objects underwater, they often appear larger and/or nearer due to the refraction of light. Light travels at different speeds in water compared to air, which causes bending as it passes from one medium to another. This bending results in visual distortions, making objects look closer and bigger than they actually are when viewed from the surface.

Understanding this phenomenon is crucial for divers as it impacts their perception of distance and size, which can affect navigation, depth judgments, and overall underwater awareness. Recognizing that objects may not be as small or distant as they seem can enhance safety and precision during diving activities.

The other answer choices do not accurately reflect this optical effect; hence they do not provide a valid description of the underwater visual experience.
