Why is the Ocean Blue?

The video explains why the sky and ocean appear blue. The sky's color is due to Rayleigh scattering, where atmospheric particles scatter blue light more than red. The ocean's blue color results from water molecules absorbing red, orange, yellow, and green wavelengths, leaving blue wavelengths to be reflected. As depth increases, only blue light penetrates, making deep ocean areas appear blue. The video also clarifies why a glass of water looks clear, as it absorbs minimal red light, undetectable by our eyes. Ocean colors can vary due to microorganisms and silt.
