Dear school leaders,
For MTLT#6, we asked you this question:

You can observe different colours of water in the figure.
Which of the indicated areas is shallower?

Correct answer: (B) Area II

Explanation:

The reason the ocean is blue is due to absorption and scattering of light. As we all know that sunlight consists of seven colors having different wavelengths. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water. In water, absorption is strong in the red and weak in the blue, thus red light is absorbed quickly in the ocean leaving blue.

Now in ocean beds, the bottom surface is not even and has different depths. The area which is at great depth, almost all sunlight that enters is absorbed, leaving a bit of blue that is why they appear dark blue to us. But in the shallower region, there is an increase in the scattering of other part of the light along with blue by the resuspension of sand and slit at the bottom surface and also many other numbers found thereby changing the color of reflected light and make it appear much lighter than the area which is deep.
