Why is the Ocean Blue?

The video explains why the sky and ocean appear blue, focusing on Rayleigh scattering for the sky and light absorption and reflection for the ocean. It details how water molecules absorb certain wavelengths, leaving blue to be reflected. The video also covers how ocean depth affects light absorption, why a glass of water looks clear, and factors causing ocean color variations.

What happens to light as it penetrates deeper into the ocean?

Why does a glass of water not appear blue like the ocean?
