Why do objects appear larger and less colorful underwater compared to above water?
Objects appear larger underwater due to the phenomenon of refraction. Refraction occurs when light moves through different media, such as water and air, causing objects to appear closer and bigger than they actually are. Additionally, the color of objects underwater appears less vibrant due to absorption. However, this does not mean that everything will be black and white; rather, the intensity of colors will be reduced compared to above water.
Understanding Refraction:
Refraction is the change in direction of light as it passes from one medium to another. When light travels from air to water, for example, it slows down and changes direction, causing objects to appear differently underwater. This is why objects may seem larger and closer when viewed underwater at a depth of 12 meters.
Color Absorption Underwater:
The absorption of colors in water also contributes to the difference in appearance of objects underwater. Light is absorbed by water, resulting in reduced intensity of colors and making objects appear less colorful when viewed underwater.
Impact on Marine Life Observation:
When diving, this phenomenon of refraction and color absorption affects how marine animals and corals appear to divers. They may seem larger and closer than they actually are, impacting the perception of size and distance while underwater.
In conclusion, the combination of refraction and color absorption affects the way objects appear underwater, making them appear larger and less colorful compared to above water. This phenomenon adds a unique perspective to underwater exploration and diving experiences.
