Answer:
It's commonly believed that the ocean is blue because it's reflecting the blue sky. But this is a misconception.
The ocean is blue because of the way it absorbs sunlight.
The white light from the sun is a mixture of all colours of the rainbow.The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light to violet light with (orange, yellow, green, blue and indigo between).
The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.
When sunlight hits the ocean, the water strongly absorbs long-wavelength colors at the red end of the light spectrum, as well as short-wavelength light, including violet and ultraviolent light. The remaining light that we see is mostly made up of blue wavelengths.Just how blue the water is depends on how much of it is available to absorb the light.
For instance, water in a glass is clear — there aren't enough water molecules to really absorb the light.
But ocean water appears bluer the farther you travel down the water column. The water molecules absorb infrared, red and ultraviolet light first, and then yellow, green and violet.
Blue light is absorbed the least, giving it the greatest ocean penetration depth.
This fact is clear if you look at unedited underwater photos that weren't taken with a camera flash or another artificial light source, even the most vibrant of tropical fish look blue.
