Why does the ocean look blue?

Answer 1

The ocean appears blue because water molecules absorb colors in the red part of the light spectrum more effectively than colors in the blue part of the spectrum. When sunlight hits the ocean, the water absorbs the red, orange, yellow, and green wavelengths, while the blue wavelengths are scattered and reflected back to our eyes, making the ocean appear blue. Additionally, the blue color of the ocean can be influenced by factors such as the depth of the water, the amount of algae and phytoplankton present, and the presence of sediments or minerals in the water.
