Question

The blue colour of the water in the deep sea is due to scattering of light.

• A. True
• B. False

Answer 1

The correct option is A True

The ocean (or sea) appears to be blue because water (like air) prefers to absorb longer wavelengths which are red and orange, and scatter shorter which is blue. As you go to further depth in the ocean, less sunlight will reach the water, less scattering occurs, making the furthest depth of the ocean appear black without artificial light.
