How does light react to water?

When light encounters water, it undergoes refraction, which is the bending of light as it passes from one medium to another due to a change in speed. This bending causes objects submerged in water to appear displaced or distorted when viewed from above the surface. Additionally, some light is absorbed by the water, especially at longer wavelengths, while shorter wavelengths may scatter, contributing to the blue color often seen in deep water.
