Answer is c bcs the bluish colour of water in deep sea is due to the scattering of light

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


The correct answer is option 'C' - scattering of light. This phenomenon is a result of the interaction between light and water molecules in the deep sea. When light enters the water, it undergoes a series of interactions and is scattered in different directions. This scattering causes the blue color to be dominant in the deep sea.

Explanation:

1. Scattering of Light:

When sunlight enters the Earth's atmosphere, it contains all colors of visible light, including red, orange, yellow, green, blue, indigo, and violet. However, as sunlight passes through the atmosphere, it interacts with air molecules, dust particles, and water droplets, causing the light to scatter in different directions. This is known as scattering of light.

2. Absorption and Reflection:

As sunlight travels through the water, different colors of light are absorbed to varying degrees by the water molecules. The molecules in the water absorb the longer wavelengths of light such as red and orange, while the shorter wavelengths, such as blue and green, are scattered more effectively.

3. Dominance of Blue Color:

Due to the scattering process, blue light is scattered more efficiently in all directions, creating a blue color that dominates the deep sea. This is why the water in the deep sea appears bluish in color.

4. Factors Affecting Color:

Several factors can influence the color of water in the deep sea. These include the presence of suspended particles, such as algae and other plants, which can absorb or scatter light, and the depth of the water. The deeper the water, the more likely it is to appear blue because more of the sunlight has been scattered and absorbed by the water molecules.

5. Reflection of Sky:

Although the reflection of the sky can contribute to the overall color of water in some cases, it is not the primary reason for the bluish color in the deep sea. The scattering of light by water molecules is the main factor that gives water its blue color.

In conclusion, the bluish color of water in the deep sea is primarily due to the scattering of light. As sunlight enters the water, the shorter wavelengths, particularly blue light, are scattered more effectively, resulting in the dominant blue color.
